First we need to find the slope, which is the incline of the line. To do this, you divide the difference of the y values by the difference of the the x values.
3-8=-5
-2-0=-2
-5/-2=5/2
To find the y-intercept, you want to find where the line hits the y-axis. Well, the point (0,8) tells us that the y-intercept is 8. The y-axis is where x=0, so our y-intercept is 8.
Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept.
