What is the difference of the x-coordinate of point A and the x-coordinate of point B?

  -3

Step-by-step explanation:

Point A is (4,3), so its x-coordinate is 4.

Point B is (7,3), so its x-coordinate is 7.

The difference of the x-coordinates in the order given is ...

  Ax -Bx = 4 - 7 = -3

Additional comment

When we say "the difference of P and Q", in math we usually mean P-Q. In everyday life, we often mean the positive difference, or |P-Q|. When talking about distances in a geometry, we usually consider distance to be positive, so perhaps the desired answer is 3, not -3.

When talking about displacement in physics, we often attach a sign. That is, A is -3 units from B.

In the above, we're taking the question at face value as a math question.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
