Which statement about proportional relationships is false? a proportional relationship must graph as a line. a graph of a proportional relationship must pass through (0, 0). each point (or pair) in a proportional relationship must share the same ratio. each point (or pair) in a proportional relationship must share the same difference.

D. Each point (or pair) in a proportional relationship must share the same difference.

Step-by-step explanation:

We know that, a proportional relationship is the one in which two quantities varies directly.

i.e. x and y varies directly if y = kx where k is a constant called 'constant of proportionality'.

As we see that the relation form of proportion is given by y = kx, which is the equation of a straight line.

So, option A is correct.

Now, when x = 0 , y =kx gives that y = 0. So, the point (0,0) satisfy the proportional relationship.

So, option B is correct,

Now, let us consider y = 2x.

So, x = 1 gives y = 2 and x = 2 gives y = 4.

This gives us that the point ( x,y ) are in the ratio x : y = 1 : 2.

So, option C is also correct.

As, we obtain the points ( 1,2 ) and ( 2,4 ) from y = 2x. The difference in these points is given by,

( 1,2 ) has difference 2-1 = 1

( 2,4 ) has difference 4-2 - 2

So, we see that the difference of points is not same for a proportional relation

Hence, option D is not correct.

I hope you do well in life :

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
