Given:
(-2, 7)
(4, 9)
x1 = -2
x2 = 4
y1= 7
y2 = 9
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 = (9 - 7)/(4 - (-2))
m = (2)/(4 + 2)
m = (2)/(6)
m = ⅓
Final answer:
The slope of the line = ⅓
