Question

If the point (7, 3) is on the graph of an equation, which statement must be true?

Answer 1

Answer:

The value of x=7 and y=3 make the equation true.

D is correct.

Step-by-step explanation:

If the point (7, 3) is on the graph of an equation.

If point lie on any graph then the value of x and y satisfy the equation. It means equation would be true for the given passing point.

First value of point is x and second value is y

For given point: (7,3)

x=7 and y=3

If we put x=7 and y=3 in the graph of the equation then equation must be true.

because it makes equation true.

For true equation left side must be equal to right side.

Hence, The value of x=7 and y=3 make the equation true.

Answer 2

The best answer would be D. because: 
1) x = 7 and y = 3 in that specific coordinate
2) if the point is on the graph and is labeled it is 1 of the MANY solutions that make that specific equation true

There is a chance for B. but if its infinate then (7,3) couldn't be the ONLY coordinate that makes it true
