Which of the following statements is false? A. In the ordered pair (3, 7), 3 is the x-coordinate.

B. The point (0, 5) is on the y-axis.

C. The horizontal distance between the point located at (3, 7) and the point located at (6, 7) is 3 units.

D. In the ordered pair (9, 7), 7 is the x-coordinate.

Its D, How do I know?

Step-by-step explanation:

Let's look at A. you start at zero and you go right three because x comes before y then go up 7 then you see that it says 3 is the x- coordinate so you know that is correct but you can't choose it. B and C they are really easy to identify as correct so you look at D and it's all wrong. So thats how its D.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
