Answer: y=6x-2
Step-by-step explanation: Make the equation 4=6(1) as you have now inputed the numbers of 1,4 into the equation 1=x 4=y and then subtract 6 both sides and you have -2
The difference between the gas prices in 2013 and 2001 is 3.00
<h3>Graphing tool</h3>
See attachment for the graph of the line of best fit
<h3>The equation</h3>
Start by calculating the slope of the line of best fit using:
From the line of best fit, we have:
The regression equation is then represented as:
So, we have:
So, the linear regression equation is:
In 2001, the value of x is 1.
So, we have:
In 2013, the value of x is 13.
So, we have:
So, the difference (d) between the prices is:
Hence, the difference between the gas prices in 2013 and 2001 is 3.00

Answer:
16. Parallelogram
17. x=3, y=9
Step-by-step explanation:
16. You should graph it to get a visual. But using the given points, you can tell that the slopes for the lines AC and BD are the same, thus meaning those lines are parallel. The same for lines AD and BC.
17. 5x+2=17, so x= 3
3y-6=21, so y=9
Hello there!
Remember that we already have one course for $35, and $22.50 for each course after that. Our total is $170.
Our equation is:
22.50x + 35 = 170
First, subtract 35 from both sides.
22.50x = 135
Divide both sides by 22.50.
x = 6
Remember to add the additional class, so x is actually 7.
Your answer is 7 courses.
I hope this helps!
