The equation of the line that is // to the given equation MUST HAVE THE SAME SLOPE.

The slope of the hiven equation is the number next to x or 3.

See it?

We know the slope is 3 and one point is given.

We now use the point-slope formula to find the equation.

y - y_1 = m(x - x_1)

See picture. The answer is y = 3x - 7.
