Best ResponseYou've already chosen the best response.0first find the slope of the line If the 2 points are (x1,y1) and (x2,y2) the slope is (y2y1) / (x2x1) here x1 = 1 , x2 = 3 , y1 = 3, y2 = 7

Best ResponseYou've already chosen the best response.0so plug these into the formula and you can work out the slope can you do that?

Best ResponseYou've already chosen the best response.1That's correct :) now you want to simplify 4/2

Best ResponseYou've already chosen the best response.1yes! :) So your slope (m) = 2 Now, since we know m = 2, we need to write an equation in slopeintercept form: dw:1433842091713:dw

Best ResponseYou've already chosen the best response.1well, Y = mx + b We know m = 2 and we can plug in the point (1,3) .. meaning x = 2, y = 3 to work out "b". 3 = 2 (1) + b 3 = 2 + b b = 1 So, y = 2x + 1 :)

Best ResponseYou've already chosen the best response.0slope = (y2  y1)/(x2x1) where (x1,y1), (x2,y2) are the coordinates through which the line passes

Best ResponseYou've already chosen the best response.0so, slope = (73)/(31) = 4/2 =2 ans @emilynicole1126
