The other person is correct the answer is C
Answer:

Step-by-step explanation:
Given
Equation: 
Required
Determine the equation of Point: (5,4)
First, we need to determine the slope of 
The general form of an equation is 
Where m represents the slope;
Hence; 
Since the equation and the point are parallel. then they have the same slope (m).

Next, is to determine the equation of the point, using the following formula:

Where

So, the equation becomes

Cross Multiply

Open Bracket

Make y the subject of formula


Hence, the equation is 
Answer:
A
Step-by-step explanation:
215.80 + 215.80 = 431.60
36.50 + 36.50 = 73
431.60 + 73 = 504.60
2560 - 504.60 = 2055.40
This one is 9.69892 x 10^2 i believe
The x will be 2.33 and the scale factor will be 1/3
