Answer:

x = 2
AC = 16

Step-by-step explanation:

The midpoint divides the segment into two equal lengths:

AB = BC

5x -2 = 9x -10

8 = 4x

2 = x

AB = 5(2) -2 = 8

AC = 2AB = 2(8) = 16

Answer:

The slope is, 3

Step-by-step explanation:

Formula for slope(m) is given by:

$m = \frac{\triangle y}{\triangle x}$

$m = \frac{y_2-y_1}{x_2-x_1}$ .....[1]

Given the statement:

$y_2 = -4$

$y_1 = 2$

$x_2 = 0$ and $x_1 = 2$

Substitute these given values in [1] we have;

$m = \frac{-4-2}{0-2} = \frac{-6}{-2}$

Simplify:

m = 3

Therefore, the value of slope is, 3
