Objective: Students will define the y-intercept in math as well as translate it to a real world meaning.
The y-intercept is where the line crosses the vertical axis/y-axis.
The real world meaning is where the price starts for example is how much the cost to start an installation or something along those lines.
Example: The line intercepts the y axis at the point (0,2), making the y-intercept 2.

Quiz:
1. Can the y-intercept be in the negatives?
2. Does the y-intercept have to be a whole number?
3. Does the y-intercept have to start at 0?
Answer key
1. Yes, the y-intercept can be in the negatives and it can pass through the negative y axis.
2. No, the y-intercept does not have to be a whole number.
3. No, the y-intercept can pass through any point on the y-axis
