B. 30 miles per hour
C. 120 miles per 4 hours
D. 180 miles per 6 hours

B

Step-by-step explanation:

The give statement is true.

Step-by-step explanation:

Yes, we can find the coordinates of any point on the xy-plane for any given equation.

For the given equation, we can take random values of x and then find the corresponding y values.

Let us prove this statement with an example.

Let us suppose, we have the equation

For x= 1, we have

Thus, the coordinate of the point is (1,4)

Similarly for other values of x, we can find the y values and can find the coordinate.

Thus, we can say that an equation allows us to find the x- and y-coordinates of any point on the xy-plane.
