The y-intercept is the point where the graph crosses the y-axis.
<em>The y-intercept of the graph is 20.</em>
From the question, we have:
This means that we have a point at (0,20)
This means that we have another point at (x,40).
Assume
So, the next point is (2,40)
This means that we have another point at (x,30).
Assume
So, the next point is (3,30)
See attachment for the graph.
