Question

What is the slope of the line with points (1, 2) and (4, 2)?


A.2


B.-3/2


C.No Slope


D.0

Answer 1

D 0

to calculate the slope (m ) use the ' gradient formula '

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (4, 2)

m = $\frac{2 - 2}{4 - 1}$ = $\frac{0}{3}$ = 0
