Answer:
The slope of the line that passes through the points (1,7) and (-4,-8) is 3.
Step-by-step explanation:
The equation of a line has the following format.

In which a is the slope.
Passes through the point (1,7)
When 
So


Passes through the point (-4, -8)
When 
So


We have to solve the following system


We want to find a.
From the first equation

Replacing in the second equation






The slope of the line that passes through the points (1,7) and (-4,-8) is 3.
