Answer:
y = 1/2x - 7
Step-by-step explanation:
y = mx + b
m (slope) = 1/2
x = 4
y = -5
<em>substitute</em>
-5 = 1/2 * 4 + b
-5 = 2 + b
-5 -2 = b
-7 = b
y = mx + b
y = 1/2x -7
Answer:

hope it helps!
Answer:
y=4
Step-by-step explanation:

8y = 32
divide both sides by 8
y = 4
Yes you have the correct one good job.
