Question

What is the slope for (-1,2) and (1,16)

Answer 1

The slope is 7.

Explanation:

(-1, 2) and (1, 16)

Slope is found using the following formula:

(y₂ - y₁) / (x₂ - x₁)

First, let's label the coordinates (these can be in any order, as long as the second numbers in each coordinate are in the y slots and the first numbers are in the x slots:

y₂: 16

y₁: 2

x₂: 1

x₁: -1

Now, substitute into the original formula:

(y₂ - y₁) / (x₂ - x₁)

(16 - 2) / (1 - (-1))

Simplify

(14)/(2)

7

The slope is 7.

Hope this helps :)
