Best ResponseYou've already chosen the best response.1The slope of the line through points (x1,y1) and (x2,y2) is given by : \(\huge m=\frac{y_1y_2}{x_1x_2}\) now,just put the values and find m.

Best ResponseYou've already chosen the best response.0It might be easier if you have a graphing calculator. Make a line that looks like: y=(2/3)x and then change the slope around a bit to figure it out and see why the slope is rise/run by going to the "trace" option on your calculator and trying things out, like when x=3.

Best ResponseYou've already chosen the best response.1Now use the first points given and the slope. Plug it into the equation: y  y1 = m(x  x1)

Best ResponseYou've already chosen the best response.1now take any point, say (5,1) and put it in y  y1 = m(x  x1)

Best ResponseYou've already chosen the best response.1Tina, let me make it easier for you. y  y1 = m(x  x1) y  (1) = 2(x  5) < Solve for y
