Find the slope of the lines joining each of the following pair of points.
(3,-2) and (4,7)

The slope of the point given is .

To find this, you use the formula (y2 - y1)/(x2 - x1). Filling in all the values leaves you with (7 - (-2))/(4 - 3). When subtracting a negative from something you simply add it to the value. So the final equation says:

(7 + 2)/(4 - 3).

Now, you solve. 7 + 2 = 9 and 4 - 3 = 1. So your slope is 9/1 or simply just 9. Heres an image to show my work for this problem. I hope this helps!
