Question

He graph of a linear function is shown.

A coordinate plane with a straight line passing through (negative 4, 2), (0, 0), and (4, negative 2).
Which word describes the slope of the line?

positive
negative
zero
undefined

Answer 1

Answer: Negative

Explanation:

use the slope formula:

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

plug in values of two points...

I will use (-4, 2) and (0,0)

⇒
`(0-2)/(0+4)`

⇒
`(-2)/(4)`

Therefore, the slope is

⇒
`-(1)/(2)`, which is negative
