we have

y=3x-1

we know that

If the point is an equation solution, it must satisfy the equation.

<u>case a</u>) (4,1)

Substitute the values of x and y in the equation

1=3*4-1

1=12-1

1\neq11 -------> the point is not solution of the equation

<u>case b</u>) (2,5)

Substitute the values of x and y in the equation

5=3*2-1

5=6-1

5=5 -------> the point is solution of the equation

<u>case c</u>) (4,3)

Substitute the values of x and y in the equation

3=3*4-1

3=12-1

3\neq11 -------> the point is not solution of the equation

<u>case d</u>) (0,-3)

Substitute the values of x and y in the equation

-3=3*0-1

-3\neq-1 -------> the point is not solution of the equation

therefore

<u>the answer is</u>

The point (2,5) is solution of the equation
