Question

What is the slope of the line that contains the points (4,8) and (9,8)? What type of line is it?

A. Slope = 0; horizontal line
B. The line has no slope; it's a vertical line.
C. Slope = 0; vertical line
D. The line has no slope; it's a horizontal line.

Answer 1

it's definitely c.slope =9; vertical line

Answer 2

For this case we have the following:

Given points:
`(x1, y1) = (4,8)` and
`(x2, y2) = (9,8)\\`

The formula of the slope is given by:

`m = ((y2-y1))/((x2-x1))\\\\m = ((8-8))/((9-4))\\\\m = (0)/(5)\\\\m = 0\\`

So, the slope is
`m = 0`and the line is a horizontal line

Answer:

Slope 0, horizontal line
