Answer:

Step-by-step explanation:
A line in 2-dimensional space has the following general equation:

Where m is the slope of the line, and b just a number
the slope can be obtaine using th following formula:

The point 2 is the one with the smallest value for x, that is (-10,-7) and the Point 1 is any other that belongs to the line, in this case, (-5,-9)

Resulting that 
To find the other term we can use any other point, I prefer us the first one so...
We have the following equation:

Resulting that b=18
I just have to eval the point (-10,-7) in the equation stated at the beginning knowin that m was calculated previously.
Answer:
Add the two equations together to eliminate y
Step-by-step explanation:
X+y=3
4x-y=7
I would use elimination since one equation has +y and one equation has -y
Add the two equations together
X+y=3
4x-y=7

5x = 10
Answer:
(x, y - 6)

Answer:
$14.656
Step-by-step explanation:
Given data
Cost of meal= $73.28
Tip= 20%
Let us find 20% of $73.28
=20/100*73.28
=0.2*73.28
=$14.656
Hence the tip is $14.656
An example of a rational expression is 2x+3/x-2.
<h3>What is a rational expression?</h3>
The complete question wasn't found. Therefore, a overview will be given. It should be noted that a rational expression simply means quotient of two polynomials.
A rational expression is a fraction whose numerator and denominator are polynomials.
In this case, an example of a rational expression is 2x+3/x-2
