Question

Find the slope of the line that contains (-1,2) and (2,2)

Answer 1

`slope=0`

Explanation:

Use the slope formula:

`(y_(2)-y_(1))/(x_(2)-x_(1))=(rise)/(run)`

Rise over run is the change in the y-axis over the change in the x-axis from one point to the other. This is also known as the "slope".

Insert the values:

`(-1_(x1),2_(y1))\\\\(2_(x2),2_(y2))\\\\(2-2)/(2-(-1))\\\\(2-2)/(2+1)\\\\`

Simplify:

`(2-2)/(2+1)=(0)/(3) =0`

The slope of the line is 0. This means that the two points lie on the same horizontal line.
