Answer
y=-$\frac{1}{2}$x+3
Work Step by Step
The point-slope form is y=mx+b.The formula for slope is m=$\frac{y2-y1}{x2-x1}$.
Using points from the graph (0,3)(2,2),
m=$\frac{3-2}{0-2}$=-$\frac{1}{2}$
Therefore the slope is -$\frac{1}{2}$.
Using the point-slope formula and (2,2):
2=-$\frac{1}{2}$(2)+b
2=-1+b
b=3
Plug these values into the point-slope form so the equation is y=-$\frac{1}{2}$x+3.
