How you can find the slope is by y2-y1 divided by X2-X1
That means it will be -1-1 divided by 3-1 = -2/2
Answer:

where

Step-by-step explanation:
we have

Let

substitute in the expression above

Solve for u
Complete the square


Rewrite as perfect squares

square root booth sides




Solve for x
Remember that

For u=3
----> 
For u=-2
----> 
Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A ( a , b) and B ( c , d )
The slope is

Answer:
see explanation
Step-by-step explanation:
For a function each value of x in the domain must map to exactly one unique value of y in the range.
This is the case here so it is a function.
The domain is the x- coordinates of the points
domain is { 5, 6, 7 }
The range is the y- coordinates of the points
range is { 2, 3, 4 }
