Answer:

  3x -7y = 0

Step-by-step explanation:

Parallel lines have the same slope.

Changing the constant in a linear equation like this only changes the y-intercept. It has no effect on the slope of the line. So, we can change the constant from 4 to 0 and we will have a line with the same slope, parallel to the original, but with a different y-intercept.

The "standard form" of the equation of a line has the leading coefficient positive. We can make that be the case by using the multiplication property of equality, multiplying both sides of the equation by -1.

Parallel line:

  -3x +7y = 0

In standard form:

  3x -7y = 0

No, because two side added up have to be greater than the other one. 5+5 is not greater than 10, it is equal.

Hence, it doesn't work.

bekas [8.4K]
If one inch represents 15 feet, then:

2 inches represent:
2 * 15 = 30 feet

1 2/3 inches represent:
1 2/3 * 15 =
= 5/3 * 15 =
= 75/3 =
= 25 feet

So the real area of the court is 30 * 25 = 750 square feet.
