Best ResponseYou've already chosen the best response.1the standard form of an equation of a line is: y = mx+b the slope of a line, m, is (change in y/change in x) = (y2y1)/(x2x1) = (21)/(31) = 1/2 you can put the coordinates of one point into the equation now to solve for b (the yintercept). y = mx+b 1 = (1/2)(1) +b 1 = 1/2 + b 3/2 = b = yintercept. so now, the standard form of an equation of a line is: y = mx+b so y = 1/2x+3/2
