The point (2,3) is on the line given by which equation below?

ANSWER

C y=x+1

EXPLANATION

If the point (2,3) lies on a given line then it must satisfy its equation.

We have to substitute the given point into each equation.

For option A, we have

y=x-1,

We plug in the values to get,



3=1, this is not true.

For option B, we have

y=-3x

3=-3(2)

3=-6 is not true.

For option C, we have

y=x+1

3=2+1

3=3 this is true.

Hence the correct answer is C

For option D, we have

y=3x

3=3(2)

3=6 this is false
