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
