what did you get after solving that formula?

good! so that's the slope for that question Now you didn't post the graph but what you can do is find 2 points where you can clearly identify the x and y values and then just do the same thing to find the slope

if x vartes directly with y then th eequation is y= mx m is the constant of variation so take -4y=8x and rearrange it to y = mx . m is oyur answer then.
