To find the slope of the line that passes through the points (7, 4) and (-10, 4), we need to apply the next formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Then, we have to label those points as follows:
(7, 4) ----> x1 = 7, y1 = 4
(-10, 4) ---> x2 = -10, y2 = 4
Then, we have:
[tex]m=\frac{4-4}{-10-7}=\frac{0}{-17}\Rightarrow m=0[/tex]Therefore, the slope is equal to zero, m = 0. It means that the line is a horizontal line.
In summary:
Slope = 0
