Find the slope of the line that passes through:<br> (-4,7) and (-6, -4)
Yuri [45]

Answer:

\frac{11}{2} or 5.5

Step-by-step explanation:

In order to find the slope of a line using two points on a graph, you must use

y_2-y_1/x_2-x_1

Pluging in the points (-4,7) and (-6, -4) to the formula you will get:

\frac{-4-7}{-6+4} =\frac{-11}{-2} =5.5

The equation for the line would be \frac{11}{2}x+29
