Answer:
y=1/2x-2
Explanation:
y=mx+b is the slope intercept form of a line.
you need to find m and b
m is the slope (rise over run) in this case it is 1 up, then over 2.
and b is the Y intercept. or in other words, the spot where the line cuts through the y-axis(vertical axis). in this case, it is -2.
