Melina graphed a line which passes through the points (-4, 2) and (6, 8). What is the slope of the line?
Ulleksa [173]

Answer:

The answer is

<h2>\frac{3}{5}  \\</h2>

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

(-4, 2) and (6, 8)

The slope is

m =  \frac{8 - 2}{6 + 4}  =  \frac{6}{10}  =  \frac{3}{5}  \\

We have the final answer as

\frac{3}{5}  \\

Hope this helps you
