You can put this solution on YOUR website!
Graph the points and draw the line between them,

You can read the slope from the line.
To go from one point to the other, move 4 units in the x, 2 units in the y.
Slope is change in y over change in x.
m=2%2F4=1%2F2
or you can solve it algebraically.
m=%28y2-y1%29%2F%28x2-x1%29=%28-2-0%29%2F%28-1-3%29=-2%2F-4=1%2F2
Then use the slope-intercept form of a line, y=%281%2F2%29x%2Bb
Use either point to solve for b.
0=%281%2F2%29%283%29%2Bb
b=-3%2F2
highlight%28y=%281%2F2%29x-3%2F2%29
