Find the slope that passes through (-7, 1), and (-4, -3)
Andrej [43]

Answer:

The answer is

<h2>-  \frac{4}{3}</h2>

Step-by-step explanation:

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

<h3>m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}</h3>

where

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

From the question the points are

(-7, 1), and (-4, -3)

The slope is

<h3>m =  \frac{ - 3 - 1}{ - 4 + 7}  =  \frac{ - 4}{ 3}  \\ =   -  \frac{4}{3}</h3>

We have the final answer as

<h3>-  \frac{4}{3}</h3>

Hope this helps you
