Question

A dance school charges a registration addition to a fee per lesson. The equation is y=30x+25 represents the total cost x lessons. What is the cost per lesson?

Answer 1

That would be the slope of this straight line; it's 30 units / lesson, e. g., $30/lesson.  The $25 is the registration and/or up-front cost.

Answer 2

The answer would be 30. You have to find the slope. You can use this formula, y=mx+b and then get the slope. $30 per lesson and the $25 is the up-front cost or the registration fee. That should help
