Answer: a. y = - 1/2x + 2
b. y = -3 + 1
Step 1: 6/5
Step 2: I Do not know
Explanation:
a. y = mx + b
The m part is the slope and the b part is the y-intercept
b. When you replace the coordinates (x and y) in the equation, you get 4 = -3(-1) + b which equals to 1 = b
Step 1. Use the rise over run equation. So you have to subtract the y coordinates on top and the x coordinates on the bottom. In this case, it's 5 - (-1) for rise and 3 - (-2) for run. In the end, the answer should be 6/5
Step 2: Sorry I do not know this one.
