Suppose the equation of the line is y = m*x + c where m is the slope and c the y-intercept. The ordered pairs are on the line so m = (2.15 - 1.10) / (21.50 - 11.00) = 1.05 / 10.50 = 0.1 So y = 0.1*x + c Now, 21.5, 2.15 is on the line so substitute these values in the above equation and solve for c: 2.15 = 0.1*21.5 + c = 2.15 + c => C = 0 So the equation of the line is y = 0.1*x or y = x/10
