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

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

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

Answer 2

Option C is correct.

Explanation:

Points given are

(1,2) and (3,8)

The formula used for slope is:

`m=(y_(2)-y_(1))/(x_(2)-x_(1))`

x₁ = 1, x₂=3, y₁=2 and y₂=8

`m=(8-2)/(3-1)\\m=(6)/(2)\\m=3`

So, slope =3

Option C is correct.
