Answer:
y = 3x + 8
Step-by-step explanation:
line a: y = 3x + 11
This means that the slope is 3 and the y intercept is 11.
(-1,5)
line b: y = 3x + b <--- we need to solve for b and plug in the numbers from the coordinates
Just plug in the numbers!
5 = 3(-1) + b
5 = -3 + b
5 + 3 = b
8 = b
The y intercept is b! So the equation is:
y = 3x + 8
