Best ResponseYou've already chosen the best response.0Basically, to find an equation of a line you can use the pointslope formula in which you need one point on the line and the slope. This is given as \[y  y1 = m (xx1)\] in which (x1, y1) is any point on the line and m is the slope. To find the slope, \[m = (y1  y2)\div(x1  x2) \] (x1, y1) and (x2, y2) being points on the line. So in your case, m = (80)/(40) = 2. So the equation is y  0 = 2 (x0) further simplified to just y = 2x
