Question

What is the slope of the shown below?

Answer 1

Answer:

B

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (3, 9) ← 2 points on the line

m = $\frac{9-1}{3-1}$ = $\frac{8}{2}$ = 4 → B

Answer 2

Answer:

B. 4

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (1, 1) and (3, 9). Substitute:

$m=\dfrac{9-1}{3-1}=\dfrac{8}{2}=4$
