Question

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

Answer 1

-1/2

Explanation:

the slope is difference in y over difference in x, so (-3-(-1))/(2-(-2)): aka -2/4 aka -0.5 or -1/2

plug in the points to find the y intercept,

the equation of the line is y = -0.5x -2 incase you need it.
