To find the slope, use the equation of a line: 
Plug in the values for x and y:

We know that 2 can fit into 5 twice, which means 2*2 is 4.
We now have
.
If 5 is b more than 4, then this means that 4 is b less than 5. Subtract 4 from both sides, and you will have b = 1.
This means your equation is y = 2x + 1.
The cost of the car is $27,546
<h3>How to calculate the cost of the car ?</h3>
The sales tax is 7%
Jorge bought a ford mustang having a sales tax of $1,928.22
Therefore the cost of the car can be calculated as follows
7/100 = 0.07
1928.22/0/07
= 27,546
Hence the cost of the car is $27,546

A is correct, D, And E.....
The general equation for any circle with its center at point (a, b) is
(x - a)² + (y - b)² = (radius)²
So the circle in the question is centered at (-3, -4), and its radius is 3 .
