Question

Find the slope of the line containing the pair of points f(7)=−4 and f(−9)=−4.

Answer 1

The slope is zero

Explanation:

Let's take f(x) = b

x= the values of x

b represents the y values

⇒ x= 7 or -4

(7,-4)⇒x1,y1

⇒x= -9 and y= -4

(-9,-4)⇒x2, y2

The slope is y2-y1/x2-x1

`(-4-(-4))/(-9-7) =\\\\(-4+4)/(-16) =\\(0)/(16) \\\\= 0`
