Answer: m = −76
Use the slope formula to find the slope m.
Slope can be found using this formula:
(x1 - x2) / (y1 - y2)
It is describing how fast the line on a graph is moving horizontally on the x axis, and how fast it's moving vertically on the y axis - basically how steep the line is.
Coordinates are written (x, y). Using the coordinates in your question (7,8) and (1,15) we can plug these into the slope equation.
