Question

May somebody help me please

Answer 1

Answer:

The answer is C because when you substituted the coordinate pairs into the equation, both sides are equal which tells you that they're a solution to the equation.

Explanation:

All you do is substitute. (x,y)

A:

Substitute

1 = 4(2) - 7

Multiply the number inside the parentheses by the outside number.

1 = 8 - 7

Subtract to get your solution.

1 = 1

Both sides equal to each other so this means that this is a solution to the equation.

B:

Substitute

9 = 4(4) - 7

Multiply the number inside the parentheses by the outside number.

9 = 16 - 7

Subtract to get your solution.

9 = 9

Both sides equal to each other so this means that this is also a solution to the equation.

D:

Both ordered pair is a solution to the equation.
