Step-by-step explanation:
First simplify your equation to make it into a y=mx+b answer and its easier to graph
y - 3 = 1/2(x+2)
Multiply numbers in parenthesis by 1/2
y - 3 = 1/2x + 1
Add 3 on both sides
y = 1/2x + 4
Your Y-intercept is 4 and the rest is how much your adding to it
That means you go Up one and 2 to the right starting from 4
