Question

Find the slope of the line that passes through the points (2.1) and (-1.-1).​

Answer 1

Answer: The slope is
`(2)/(3)`

Explanation:

The slope can be calculated with the following formula:

`m=(y_2-y_1)/(x_2-x_1)`

Then, knowing that the line passes through the points (2,1) and (-1,-1), we can substitute the coordinates into the formula.

In this case:

`y_2=-1\\y_1=1\\x_2=-1\\x_1=2`

Therefore, the slope of the line that passes through the points (2,1) and (-1,-1) is:

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