Given:

(-3, 7)

(1, 15)

x1 = -3

x2 = 1

y1= 7

y2 = 15

Find the slope of the line.

Formula for the slope of the line:

m = change in y/ change in x

m = (y2 - y1)/(x2 - x1)

Solution:

Substitute the given values to the formula for the slope of the line.

m = (y2 - y1)/(x2 - x1)

m = (15 - 7)/(1 - (-3))

m = (15 - 7)/(1 + 3)

m = (8)/(4)

m = 4

Final answer:
The slope of the line = 4
