m=(y2-y1)/(x2-x1) (Multiplied terms on both sides of equation by (x2-x1).)
m(x2-x1)=y2-y1 (Added y1 to both sides of equation, ultimately isolating y2.)
y2=m(x2-x1)+y1
To solve for y2 in the equation m = (y2-y1)/(x2-x1), isolate y2 by **multiplying both sides **by (x2-x1) and then adding y1. ;
To solve for y 2 in the slope formula, rearrange the equation to isolate y 2 : y 2 = m ( x 2 − x 1 ) + y 1 . This provides a way to calculate y 2 based on the values of the slope m and the coordinates of the points.
