First, find the slope of the line that passes through the given points using the slope formula:
[tex]m=\frac{\Delta y}{\Delta x}[/tex]Next, substitute the value of the slope and the coordinates of one of the given points into the slope-intercept form of the equation of a line to find the y-intercept b:
[tex]y=mx+b[/tex]Compute the value of the slope:
[tex]\begin{gathered} m=\frac{(-2)-(1)}{(3)-(-4)} \\ =\frac{-2-1}{3+4} \\ =\frac{-3}{7} \\ =-\frac{3}{7} \end{gathered}[/tex]Replace m=-3/7, x=-4 and y=1 into the slope-intercept form of the equation of a line:
[tex]\begin{gathered} \Rightarrow1=-\frac{3}{7}(-4)+b \\ \Rightarrow1=\frac{12}{7}+b \\ \Rightarrow1-\frac{12}{7}=b \\ \Rightarrow-\frac{5}{7}=b \\ \therefore b=-\frac{5}{7} \end{gathered}[/tex]Replace m=-3/7 and b=-5/7 to get the equation of the line through the points (-4,1) and (3,-2):
[tex]y=-\frac{3}{7}x-\frac{5}{7}[/tex]Therefore, the answer is:

When we are doing divisions with fractions, the best thing to do is also write the division as a fraction like this:
[tex]\begin{gathered} \frac{13}{10}\frac{\cdot}{\cdot}\frac{2}{10} \\ \Rightarrow\frac{\frac{13}{10}}{\frac{2}{10}} \end{gathered}[/tex]Now, we multiply 13x2 and put it in the numerator, and 10x2 in the denominator:
[tex]\frac{\frac{13}{10}}{\frac{2}{10}}=\frac{13\cdot10}{2\cdot10}[/tex]Then we solve and simplify if needed:
[tex]\frac{13\cdot10}{2\cdot10}=\frac{130}{20}=\frac{13}{2}[/tex]therefore, the answer is 13/2
Write an equation in slope-intercept form of the line that contains the points in the table.
Answers
Step 1. We are given a table of (x, y) values and we need to select the option that represents the slope calculation.
First, we remember the formula to calculate the slope:
[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]Where (x1, y1) and (x2, y2) are two points or sets of values given for the line.
Step 2. In the numerator of the slope formula, we have a subtraction between y-values.
In the table, the y-values are:
Therefore, in the numerator of the calculation, we must have a subtraction between two of these numbers. This discards options A, and B.
Step 3. In options C and D we have this:
[tex]C.\frac{9-(-3)}{1-(-2)}[/tex][tex]D.\frac{-3-11}{-2-4}[/tex]In option C, there is a correct subtraction of 9 and -3, but in option D, the correct subtraction would be -3-(-11). Therefore option D is also discarded and the correct answer is C.

Would we use ">" or "<" to replace the in 5.1489 ? 5.2019. Write only the symbol that is true.
Answers
5.1489 is less than 5.2019
Therefore, the symbol between the two decimals would be less than symbol.
That is,
[tex]5.1489<5.2019[/tex]The symbol that would replace ? is <
Upon replacing the symbols, the equation would look like:
5.1489 < 5.2019
Hence, “<“ is the symbol that would take the place of the question mark.

SOLUTION:
Step 1:
In this question, we are given the following:
A scientist has discovered a new strain of bacteria.
The bacteria grows exponentially at a rate of 68% each hour as shown in the table below.
Identify the equation used to calculate the growth, and estimate the population of the bacteria when the time has reached 10 hours.
Step 2:
The details of the solution are as follows:
Since the bacteria grows exponentially at a rate of 68% each hour, and the initial population is 1. 2 billiion.
This means that:

Answers
Given:
The ratio of the three angles is 4:9:5.
To find the largest angle:
Let the first, second, and third angles be,
[tex]\begin{gathered} \angle1=4x \\ \angle2=9x \\ \angle3=5x \end{gathered}[/tex]Using the angle sum property of a triangle we get,
[tex]\begin{gathered} \angle1+\angle2+\angle3=180 \\ 4x+9x+5x=180 \\ 18x=180 \\ x=10 \end{gathered}[/tex]So, the largest angle is,
[tex]\begin{gathered} 9x=9\times10 \\ =90 \end{gathered}[/tex]Hence, the measurement of the largest angle is 90 degrees.

Given that

[tex]\begin{gathered} d=79=0.1(79)=\text{ \$7.9} \\ q=130=0.25(130)=\text{ \$32.5}0 \\ n=26=0.05(26)=\text{ \$1.30} \end{gathered}[/tex]8. Marcy is a real estate agent. She sold a house for $356,700. Her commission from that sale was $12,484.50. What is her commission rate?

Answers
The reflection on the left (known as the pre-image) has dimensions clearly given, while the shape on the right (known as the image) has no dimensions given but, a careful observation shows that the scale factor is the same, that is, 1 : 1.
This means the sides and angles do not change value(s). The image simply lies in a different location, that is, a different quadrant. The shape, the size and the orientation has not changed which means the dimensions in the image is the same as the pre-image.

Based on the graph of the function shown, we can logically deduce the following information:
A. The domain can be best described using interval notation. The domain is (-∞, ∞).
B. The range can be best described using the roster method. The range is {y | y = -∞, -3}.
How to identify the domain and range of this graph?The horizontal extent of a graph represents all domain values and they are also read and written from smaller to larger numerical values, and from the left of the graph to the right.
Similarly, the vertical extent of a graph represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.
By critically observing the graph of the continuous function shown above, we can reasonably infer and logically deduce the following information:

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.
Probability of any event is greater than or equal to zero and less than or equal to 1.

For P(9)
Number of favourable outcomes = 0
P(9) = 0
For P(odd number)
