Given:
(-4, 4)
(-1, -2)
x1 = -4
x2 = -1
y1= 4
y2 = -2
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 = (-2 - 4)/(-1 - (-4))
m = (-6)/(-1 + 4)
m = (-6)/(3)
m = -2
Final answer:
The slope of the line = -2
