Step-by-step explanation:
Hello! I see your teacher is a Harry Potter fan. Anyways,
1) The y-intercept is when you plug x as 0 or it's when the line crosses the y axis. The easiest way to find the y-intercept is to look at the graph and see where the graph starts off from the y axis.
We can see that the line starts off from (0,0) so the y-intercept is (0,0).
In this case, the y-intercept represents the initial income when you haven't start working yet.
2) The formula for slope is y2-y1/x2-x1. We can find any two points on the line to do this equation. Lets take (0,0) and (2,30).
Let's now plug in the y, 30 - 0
And then the x, 2 - 0
Together they are 30 - 0/ 2 - 0
Or 30/2 = 15.
The slope is 15
In this case, the slope represents the amount of income earned per hour/every hour.
