A slope of zero indicates that the line is horizontal, parallel to the x-axis and passes through all points in the plane with the same y-coordinate.

For the 2 given points both y-coordinates are - 8 and so the equation of the line is

y=-8

.

If you note this fact then it can be stated that the slope is zero without using the gradient formula.

Answer:

[tex]\frac{-7}{17}[/tex]

Step-by-step explanation:

To find the slope simply use the rise over run.

The change in y value (rise) from (7,1) to (-10,8) is y=1-8

The change in x value (run) from (7,1) to (-10,8) is y=7-(-10)

As a fraction this can be modeled by [tex]\frac{1-8}{7-(-10)}[/tex]

[tex]\frac{-7}{17}[/tex] is the slope as it is rise over run and cannot be simplified further.
