Can someone help me find the slope passing through the points (8,18) and (7,7)?

Such problems can be solved by taking y2 - y1 and dividing by x2 - x1.

(18 - 7) / ( 8 - 7) = 11 / 1

So, the slope is 11.

You need to use the formula:
m = (y2 - y1/x2 - x1).

Then you plug the numbers in:
m = (18 - 7/8 - 7)

So, the answer is:
11/1 OR 11.

Use this formula for finding slopes.

M = y2 - y1/(x2 - x1)

(x1,y1) (x2,y2)
8 18 7 7

y1 = 18
y2 = 7
x1 = 8
x2 = 7
M = 18 - 7/8 - 7
M = 11/1 or 11
