Question

You can either make a graph or write a ratio to find the slope

Answer 1

The slope is:

• m = 2

Explanation:

Given the table

Pounds, x 3 4 5 6

Cost, y 6 8 10 12

Taking any two points let say (3, 6) and (4, 8)

`\mathrm{Slope}=(y_2-y_1)/(x_2-x_1)`

`\left(x_1,\:y_1\right)=\left(3,\:6\right),\:\left(x_2,\:y_2\right)=\left(4,\:8\right)`

`m=(8-6)/(4-3)`

Refine

`m=(2)/(1)`

`m = 2`

Therefore, the slope is:

• m = 2
