[tex]y=mx+b[/tex]
m is the slope and b will be the y-intercept
Slope is going to be m = 1/2
Y-intercept is b = -3
You can figure out the slope by doing rise over run on the graph, and seeing where the line hits the y-intercept, which is -3
Plug it into the equation.
Answer:
[tex]y=\frac{1}{2} x-3[/tex]
