y=-1/3x - 19/3

Explanation:

Let's start off with point-slope form.
(y-y_1)=m(x-x_1)
where y_1 and x_1 are points on the line and m is the slope.
We can plug in the information we have into this equation.
y-(-7)=-1/3(x-2)
or
y+7=-1/3(x-2)
If you want to convert this to slope-intercept form, you would simply solve for y
y+7=-1/3x+2/3

y=-1/3x - 19/3
