Question

What is the slope of the line that passes through the points (9, -10) and (14,5)?

Write your answer in simplest form.

Answer 1

`m=3`

Explanation:

`\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=(y_2-y_1)/(x_2-x_1)`

`\left(x_1,\:y_1\right)=\left(9,\:-10\right),\:\left(x_2,\:y_2\right)=\left(14,\:5\right)`

`m=(5-\left(-10\right))/(14-9)`

`\mathrm{Refine}`

`m=3`

Answer 2

3

Explanation:

so you have to use the equation

y2 - y1 / x2 - x1

to find the slope

now all you have to do is substitute

-10 - 5 / 9 - 14

-15/ -5
