Question

Joan has some photos in her photo album. Each week she plans to add 12 photos. After 8 weeks, Joan has 120 photos. The equation y = 24 + 12x represents the equation. What does the y-intercept mean in this context?

Answer 1

Explanation:

The y intercept occurs when x = 0

What you are left with is 24.

24 is the number of photos she started with. She started with 24 photos before she added any in any of the weeks that followed.
