Question

Luke goes to the fair with $50.Each rife cost $2. if an equation is written to show. how much money Luke has at the end of the day, what is the slope and y-intercept

Answer 1

Let's define the next variables

x: number of rides

y: amount of money left

Each ride cost $2. Then, x rides cost 2x dollars.

In the beginning, Luke has $50, but after x rides he will have 50 - 2x dollars

Therefore, the equation is:

y = 50 - 2x

where the y-intercept is 50, and the slope is -2
