Question

For the graph of the equation you wrote in Item 3, what does the y-intercept represent?

A) Amount already saved
B) Total cost of the bike
C) Amount saved each week
D) Weeks it takes to save enough

Answer 1

The y-intercept represents the value of the dependent variable when the independent variable is zero.

Step-by-step explanation:

The y-intercept, a, of a graph tells us the value of the dependent variable (y) when the independent variable (x) is equal to zero.

In the context of the equation mentioned in Item 3, where the y-intercept is 50, it represents the point on the graph where the dependent variable (y) would be 50 when the independent variable (x) is zero.
