We are given : Kaser needs to pay total = $155.
Amount she has already = $35.
Saving of each week = $15.
Therefore, the coordinate for initial saving for 0 number would weeks would be (0,35).
For first week saving would be 35+15 = 50
So, the coordinate would be (1,50).
We got two coordinates on the graph.
We need to join the coordinate to draw a segment for y=0 to y=155.
Because total saving should be $155.
After plotting points and draw a segment, we can see that for 8 weeks the total saving would be $155.
