Question

What is the slope of the line passing through (1, 2) and (3, 8)?
slope = 1/17
slope = 1/3
slope = 3
slope = 7

Answer 1

Answer:

Option C is correct.

Step-by-step explanation:

Points given are

(1,2) and (3,8)

The formula used for slope is:

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

x₁ = 1, x₂=3, y₁=2 and y₂=8

$m=\frac{8-2}{3-1}\\m=\frac{6}{2}\\m=3$

So, slope =3

Option C is correct.

Answer 2

Answer:

The slope of the line passing through (1,2) and (3,8) is 3.

Step-by-step explanation:

Slope formula is y2-y1/x2-x1

y2=8

y1=2

x2=3

x1=1

8-2/3-1

8-2=6

3-1=2

6/2=3
