Find the slope of the line passing through the points (-2,5) and (3/2, 2).
sveticcg [70]

Answer:

The answer is

<h2>-  \frac{6}{7}</h2>

Step-by-step explanation:

The slope of the line passing through two points can be found by using the formula

<h3>m =   \frac{y2 - y1}{x2 - x1}</h3>

where

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

From the question

The points are (-2,5) and (3/2, 2)

The slope is

<h3>m =  \frac{2 - 5}{ \frac{3}{2}  + 2}    \\  =   -  \frac{3}{ \frac{7}{2} }  \\  = -  3 \div  \frac{7}{2}  \\  =  - 3 \times  \frac{2}{7}</h3>

We have the final answer as

<h3>-  \frac{6}{7}</h3>

Hope this helps you
