Cross multiply.

4(x - 8) = 5(2)

4x - 32 = 10

4x = 42

x = 42/4

x = 21/2

x = 10.5

Find the slope of the line given two points:

vesna_86 [32]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(8, 10) and (-7, 14)

The slope is

$m = \frac{14 - 10}{ - 7 - 8} = \frac{4}{ - 15} = - \frac{4}{15} \\$

We have the final answer as

$- \frac{4}{15} \\$

Hope this helps you
