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)
