Answer:
Part a) The constant of variation is 
or 
Part b) 
Step-by-step explanation:
Part a) Find the constant of variation.
we know that
The simple interest formula is equal to
In this linear direct variation the constant r represent the constant of proportionality
where
I is the Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute the values and solve for r
Part b) what will the interest be after 3 years
in this part we have
substitute the values
Quantitive since it can be counted
The 2 horsepower is equal to 1492 watts.
Given that horsepower and watts are units of measure of power and they are directly proportional such that 5 horsepower is equal to 3730 watts.
Horsepower is a unit of measurement of power, or speed at which work is done, usually related to the power of an engine or motor. power is calculated by multiplying force (in pounds) by speed (in feet per second).
Let H= horsepower, W=watt
As we are given horsepower is directly proportional.
So, the relation is W=kH where k is constant.
Here, H=5 and W=3730.
By substituting the value of W and H we will find the value of k, we get
3730=k×5
3730/5=k
746=k
Now, substituting the value of k in relation and we get
W=746H
We have to find the power of 2 horsepower.
So, we will substitute H=2 in above relation, we get
W=746×2
W=1492 watts.
Hence, the 2 horsepower is equal to 1492 watts when 5 horsepower is equal to 3730 watts.

You need to simplify the expression and then you will know what the y coordinates are. I’m not good at this But you just need to solve the equation to be able to get the same coordinates by themselves. It’s sorta like geometry and algebra mixed. But first simplify the equations and then that will really help you.
Have a great day!
