Question

Calculate the slope of the line passing through the two colored points below (-1 , 1) (1, 1)

Answer 1

Slope is defined as the change in y with respect to the change in x.


`m = (y_2 - y_1)/(x_2 - x_1)`

Plug in the values.


`(1 - 1)/(1 - (-1)) = (0)/(2)`

So, the slope is equal to 0. Which means its a horizontal line.
