In y = -2x + 2, which of the following statements must be true about the
equation? (Check all that apply)
A) The slope is -2.
B) The equation represents a quadratic function.
C) The y-intercept is (0,-2).
D) From left to right, the line is decreasing or moving in a negative direction.
Hi there!
»»————- ★ ————-««
I believe your answer is:
A) The slope is -2.
D) From left to right, the line is decreasing or moving in a negative direction.
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
The equation given is in 'Slope-Intercept Form', where the equation gives the slope and y-intercept of a linear line. This would eliminate option B, since it is not quadradic.⸻⸻⸻⸻
[tex]\boxed{\text{Slope-Intercept Form is:}}\\\\y = mx + b\\\\\rightarrow m - slope\\\\\rightarrow b - \text'y-intercept\text'[/tex]
⸻⸻⸻⸻
In the equation [tex]y= -2x+2[/tex], the slope is '-2' (-2 takes m's place) and the y-intercept is (0,2). (2 takes b's place.)This would mark option A as a correct answer and eliminate option C. Line with negative slopes would go down if you were looking at the graph from left to right. Since the sign of the slope is negative, this would make option D a correct answer as well.⸻⸻⸻⸻
Options A and D should be correct.

Hope this helps you. I apologize if it’s incorrect.

Help what is the slope of the line?
9514 1404 393
Answer:
8/5 = 1.6
Step-by-step explanation:
It looks like the line crosses grid points (-4, -4) and (1, 4). This means the slope is ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-4))/(1 -(-4)) = 8/5 = 1.6
The slope of the line seems to be about 8/5, or 1.6.

What is the y-intercept of the line that has a slope of -1/2 and passes through the point (2, 3)?
y=-1/2x+
=========================================================
Explanation:
For now, let's call the y intercept b
We'll plug in x = 2 and y = 3 from the given point to find b
y = mx+b
y = (-1/2)x + b
3 = (-1/2)*2 + b
3 = -1 + b
3+1 = b
4 = b
b = 4
The y intercept is 4
The equation of the line is y = (-1/2)x + 4
diameter 8 inch circle and round to the nearest hundred
Step-by-step explanation:
I think we need to area
Radius = Diameter/2
Radius = 8/2
Radius = 4 in
Area = πr²
Area = 22/7 × (4)²
Area = 22/7 × 16
Area = 50.28 in²
Step-by-step explanation:
According to question,
Diameter=8 inches
Therefore, Radius=D/2=8/2 inches=4 inches
Now,
To find perimeter,
2πr
2×22/7×4 inches
25.1428571 inches
To find area,
πr²
22/7×(4 inches)²
22/7×16 inches²
50.2857143 inches²

What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
Point P is,
P = (2, - 1)
Now, We know that;
To rotate quadrilateral ABCD 90° counterclockwise about the origin we will use the rule (x, y) becomes (-y, x).
Hence, The value of the image of P under the rotation 90 degree counter about the origin is,
= (- (- 1), 2)
= (1, 2)
Thus, The value of the image of P under the rotation 90 degree counter about the origin is, (1, 2)
