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.
