Best ResponseYou've already chosen the best response.2collinear means all the points are on the same line so find the equation of the line using the points R(6,4) and Q (4, 3) when you get the equation use the 3rd point P(2, b) by substituting x = 2 into the equation to find y the value of y, will be b. An alternate solution is to plot the 2 points on the number plane, draw a line through them and see what the y value is when x = 2 hope it helps
