Answer
(2,3)
Step-by-step explanation:
9x-7y=-3
-9x+15y=27
-------------------
8y=24
divide by 8 on both sides
y=3
now using substitution, you can now work out x
9x-7y=-3
9x-7(3)=-3
9x-21=-3
add 21 on both sides
9x=18
then divide my 9 on both sides
x=2
finito ; )

Answer:
648
Step-by-step explanation:
Identify the slope and y-intercept of the line on the graph. Then, write the equation of the line in slope intercept form. I need all of the answers (all 9 - 12). It'd help me a lot. Thanks.
Answer:
9: Slope is 2/5 and y-intercept is -3
Equation: y=2/5x-3
10: Slope is 1 and y-intercept is -6
Equation: y=x-6
11: Slope is -1/4 and y-intercept is 5
Equation: y=-1/4x+5
12: Slope is 4/3 and y-intercept is 0
Equation: y= 4/3x + 0
Sorry for not explaining the answers! I was in a bit of a rush, but if you don't understand just let me know by rating my answer because I'd be happy to help! (another day though, I'm full of exams these next 2 weeks hehe)
