Slope is the relationship between vertical gain and horizontal gain. Slope tells you how fast you are going up (or down in the case of a negative number) in relationship to how fast you are moving horizontally. If you gain one unit of elevation (the y-axis) for every unit of horizontal movement (the x-axis) your slope is one.

The formula for slope is slope = gain in y divided by gain in x = y2-y1/x2-x1, where 2 is the second position and 1 is the original position. This change in position is often represented by the Greek letter delta which looks like a triangle.

For your first set of points, slope = 9-4/3-1 = 5/2 = 2.5
For your second set of points, slope = -2-7/-5-(-9) = -9/4 = -2.25

Are you getting this?

Formula for a slope=
(1,4) (3,9)
slope=
slope=
and
(-9,7) (-5,-2)
slope=
slope=
and
(3,-6) (3,4) and
slope=
slope=
zero slope = undefined
(4,-3) (-1,-3)
slope=
slope=
zero slope=undefined
Hope you understand
=)
