Answer:
Paralellogram
Step-by-step explanation:
Because the figure we get after drawing in a graph has parallel lines
It takes the son one and half hours to clean the house. To find this you need the equations F+S=2 and F+1=S. (F=father and S=son) You take the F+1 and substitute it in for S in F+S to get F+(F+1)=2. Then you combined like factors, 2F+1=2, and simplify to get F=.5hr. After this you plug .5 in to F+1=S to get (.5)+1=S, meaning it takes the son 1.5 hour to clean the house.

Given:
A surf instructor has an initial fee of $12 and charges $8 per hour for lessons.
To find:
The y-intercept and its location on the graph.
Solution:
Initial fee = $12
Variable fee = $8 per hour.
Let the total fee be y for x hours. Then,
Put x=0, to find the y-intercept.
Therefore, the y-intercept is 12.
Table of values for ,
x y
0 12
-1 4
Plot (0,12) and (-1,4) on a coordinate plane and connect them by a straight line.
Clearly, the y-intercept is located at (0,12).
