Answer:

Step-by-step explanation:
The slope formula is:

where (x₁, y₁) and (x₂, y₂) are the points the line passes through.
The points given are: (-7,-2) and (-6,7). Therefore,

Substitute the values into the formula.


Solve the numerator by adding 7 and 2.

Solve the numerator by adding 7 to -6.

Divide 9 by 1.

The slope of the line is 9.
