Question

Jamal pays an initial fee of $50 and $4.00 for each audio book he downloads?

Let x=number of audio books
Let y=total cost in dollars

Write an equation for this situation.
What is the meaning of the slope and the y intercept?

if you answer this and show the work I'll give out 50+ points on a different question that you don't even have to answer for now this question is 25​

Answer 1

4x + 50 = y

Explanation:

Since it is $4 for each audiobook, this means that it is the slope.

Since Jamal started with an initial fee, this makes it the y-intercept.

So the equation is $4 per audiobook = 4x, initial fee of $50 which makes the equation: 4x + 50 = y

Y-intercept is the starting number, in this case, the initial fee.

Slope is the rate at which a value is increasing, in this case, for each audiobook bought, $4 is spent
