one line passes through the points G(-1,5)and H (2,9). a second line passes through the points x(-3.-2) and y (5,12). which line has a greater slope? explain how you can tell by graphing the two lines. explain how you can tell bby calculating the slopes of the lines

    ok so by graphing you would need to graph the points properly and then draw a line going through the points GH and XY. From here you look at which line has a greater "slope" meaning that you look at the line that has a higher angle from either the x or -x axis. this will make more sense once we get into the actual solution. So the actual solution is the following: For finding the slope we do the following ... slope = rise / run = G(rise) - H(rise) / G(run) - H(run) = 5 - 9 / -1 -2 = -4 / -3 = 4/3. So you can plot the line y = (4/3)x on the graphing paper. Now to find the slope of the second line. slope = rise / run = x(rise) - y(rise) / x(run) - y(run) = -2 - 12 / -3 -5 = -14/-8 = 14/8 = 7/4. So you can plot the line y = (7/4)x on the graphing paper. Now if you actually put those two lines on the same graph you will see that the line with the slope of (7/4) is steeper than the line of the slope (4/3). Therefore, you can say that line y = (7/4)x has a greater slope than line y = (4/3)x
