Question

What is the slope of the line that passes through (-3,2) and (1,2)

Answer 1

slope of a line through two points m=
`(y2-y1)/(x2-x1) = (2-2)/(1-(-3)) = (0)/(4) =0`

Answer 2

(-3,2)(1,2)...notice that the y values are the same.....when the y values are the same u have a horizontal line with a 0 slope.

IF the x values would have been the same (instead of the y values), then u would have had a vertical line with an undefined slope.
