The graph below shows a proportional relationship between y and x.

ALSO Answer not 1/40

2/40 maybe

Step-by-step explanation:

Explanation:

You haven't posted the full question, but I'm assuming you're looking for the proportionality constant k. If this assumption is correct, then you have the right idea, but instead of 1/40, you should have done 40/1 = 40.

This is because the point (x,y) = (1,40) is then used to compute the k value to be

k = y/x = 40/1 = 40

You could also use a point like (2,80) to get the same thing

k = y/x = 80/2 = 40

You can use any point on the blue line as long it's not the point (0,0). This is because dividing by zero is not allowed.

Side note: The equation of this line is y = 40x. It is in the form y = mx+b with m = 40 as the slope and b = 0 as the y intercept.

could you reply to this with the question so i can ?

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
