The vertices of a square are its endpoints
The coordinates of the other pairs are: (-1, 3), (4, 3) and (-1, -7), (4, -7)
The given parameters are:
Calculate the distance EF
So, we have:
Add 5 to the y-coordinates of E and F
Subtract 5 to the y-coordinates of E and F
Hence, the coordinates of the other pairs are: (-1, 3), (4, 3) and (-1, -7), (4, -7)
There is no third pair

Answer:
Step-by-step explanation:
Use the slope-intercept form:
m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run ( ).
If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:
Now find the slope. Use the slope formula:
You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:
The slope is 3. Insert this value:

Given:
Charlie bought a new computer for $450 with his credit card.
He plans to pay the minimum payment of $25 per month.
To find:
The rate of change.
Solution:
Let y be the remaining amount of loan after x months.
Initial amount of loan = $450
Payment of one month = $25
Payment of x months = $25x
Now,
Remining amount = Initial amount of loan - Payment of x months
...(i)
The slope intercept form is
...(ii)
where, m is slope and b is y-intercept.
From (i) and (ii), we get
Therefore, the rate of change is -25 dollars.
