Asked by wiki @ in Mathematics viewed by 232 People


Which is the slope of the line that passes through the points (−3,1) and (4,−2)?

Slope = -3
Slope = 1/2
Slope = -3/7
Slope = -7/3

Answered by wiki @



Hello!

Here is the formula for finding slope:

y₂ - y₁
x₂ - x₁

OR

difference in y
difference in x
__________________________________________________________

y₂ = -2
y₁ = 1

(-2) - 1 = -2 + -1 = -3

x₂ = 4
x₁ = -3

4 - (-3) = 4 + 3 = 7

That equals: -3/7

\framebox{Slope = -3/7}
