Write the slope-intercept equation (8th grade math/algebra 1)

How to write the equation of a line in the slope-intercept form if you're given a point on the line and the slope? You could use the point-slope formula, but in this video I show you a way to do it without that formula. It is based on the fact that any point on the line fulfills the equation of the line. We also look at a real-life example concerning the price of shampoo bottles.
