What is the equation in point-slope form of the line passing through (−2, 0) and (2, 8)?

To express the equation in a point-slope form, obtain first the slope of the line between the points. The slope, m, of this line is,

                                  (y2 - y1)/(x2 - x1) = (8 - 0)/(2--2) = 2

The point-slope form of the line is generally expressed as

                                         y - y2 = m (x - x2)

Thus, in this given the point-slope form is, 

                                           y - 8 = 2 (x - 2)

That’d be 9 years or something
