Answer: Down below
Step-by-step explanation:
We know that 11.9% is the same as .119
The price increase = .119 * 58000 = 6902
The price of the new model is 6902+ 58000
The first and the 2nd one are correct because x is 21 and y is 49
3 and 4 at wrong
The values of 
and 
are 
and 
, respectively.
In this question we need to solve the linear equation for each point, first for 
and later for 
.
If we know that , then the value of is:
If we know that and , then the value of is:
The values of and are and , respectively.

Answer:
A
Step-by-step explanation:
X values cannot repeat in a function, 3 is used as an X value twice in A, and therefore cannot be a function.
If this is graphed, you can use the vertical line test, if a vertical line on any point goes through other points, it is not a function.
In this case, just check if X repeats.
