Question

A line contains the points (8, 5) and (6, 15).

Using the slope formula, what is the slope of the line?

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

Answer 1

Answer: -5

Explanation:

The formula for calculating the slope of a line is given as :

m=\frac{y_{2} }{x_{2}} - \frac{y_{1}}{x_{1}}

`x_(1)` = 8

`x_(2)` = 6

`y_(1)` = 5

`y_(2)` = 15

substituting into the formula , we have

m =
`(15-5)/(6-8)`

m =
`(10)/(-2)`

m = -5

Therefore the slope is -5
