Question

What is the slope of the line through P(2, 8) and Q(0, 8)?

Answer 1

0

Explanation:

The formula for slope is:

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

where:
m = slope
`(x_"1", y_"1")=(0,8)`
`(x_"2", y_"2")=(2,8)`

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

`m=((8)-(8))/((2)-(0))`

`m=0/2`

`m=0`

Since the slope is 0, this means that the y values do not increase, but remain constant. Instead, only the x values decrease and increase.

Here is a graph of of the linear equation:
