Question

Refer to the data above. What number represents the slope of the line, if the points on the graph above were joined?

Answer 1

Answer:

slope = 40

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, 80) and (x₂, y₂ ) = (4, 160) ← 2 points on the line

m = $\frac{160-80}{4-2}$ = $\frac{80}{2}$ = $\frac{40}{1}$ = 40
