Answer:

B. 4

Step-by-step explanation:

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

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

[tex]m=\dfrac{9-1}{3-1}=\dfrac{8}{2}=4[/tex]

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 = [tex]\frac{9-1}{3-1}[/tex] = [tex]\frac{8}{2}[/tex] = 4 → B
