Answer: The slope of the line that contains the points (1, -19), (-2,-7) is -4.
Explanation:
When finding the slope of two given coordinate pairs, we can use the rise over run method.
(1, -19), (-2,-7)
==> y2-y1/x2-x1
Let us make the pair (-2,-7) y2 and x2 and the pair (1, -19) y1 and x1.
Inserting the values into the equation;
==> -7 + 19/ -3
==> 12/-3
==> m = -4
The slope of the line that contains the points (1, -19), (-2,-7) is -4.
