  1. Two ways:
    (1) Plot y = 3x - 5 and check if it passes through the point (4,7).
    (2) Substitute the x-coordinate of the point given (which is 4) to the equation, and solve for y. If the resulting y is equal to 7, it is a solution to the equation.

    Let's do #2 to check:
    y = 3x - 5
    y = 3*4 - 5
    y = 12 - 5
    y = 7
    therefore, it is indeed a solution to the equation.
