X=7 5x8 is 40x and 5x4 is 20 take away 20 from both sides so it looks like this 40x=280 then divide by 40
Answer:
y = 9x+80
Step-by-step explanation:
We can use the slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
y = 9x+b
Substitute the point in for x and y
-1 = 9(-9) +b
-1 = -81 +b
Add 81 to each side
-1+81 = b
80 =b
The equation is y = 9x+80
Answer is 2 because it’s true
