Answer 1

Answer:

z=-3

Step-by-step explanation:

The given line has slope m=-7.

The line passes through (-1,-8) and (z,6).

We use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

We substitute $x_1=-1$, $y_1=-8$, $x_2=z$ , $y_2=6$ and $m=-7$ to get:

$-7=\frac{6--8}{z--1}$

$-7=\frac{6+8}{z+1}$

$-7=\frac{14}{z+1}$

$-7(z+1)=14$

Expand $-7z-7=14$

$-7z=14+7$

$-7z=21$

$z=-3$
