Answer :
Slope intercept form is y=mx+b m=slope, b=y-intercept
13-18 Solve the equations so that y is by itself.
19-21 Plug in the slope, and plug in the points for x and y, then solve for b.
22 Find the slope, then plug in the points for x and y, and solve for b.
23 There is no slope, so it is just y=-5
24 Slope is zero, so it is just x=-4
