Answer:
y=1/2x-4
Step-by-step explanation:
You are given the slope, 1/2. So you can plug it into the equation (y=mx+b)
You also need to plug in the x and y coordinate your given so you'll have
-3=1/2(2)+b. Then you solve for b, which is -4. You now have your answer, y=1/2x-4.
Step-by-step explanation:
|5| - |-3| is 2
The answer to -2(x-8) is 16-2x
