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

I'd suggest re-wording your question:
"How do I find the ordered pair (x,y) that solves this system of linear equations?"
One way of doing that would be to substitute y=5x+7 into the other equation:
-3x - 2(5x+7) = -12. Solve this for x. Once you have a value for x, subst. that value into y=5x+7 to find the corresponding y value.
Then write the ordered pair (x,y). That's it.
Answer: 2005
Step-by-step explanation: Because, each year it goes down 4, but 50-4=46 not 44. I hope this helped!
Answer:
The initial distance between Wade and Alexandra is 240ft.
They walk towards each other.
Alexandra walks twice as fast as Wade.
Now, because they are walking towards each other, when the distance walked by both of them equals 240 ft, they will meet.
Then:
if Wade walks z ft, Alexandra walks 2*z ft.
So we have the equation:
Distance that Wade walked + Distance that Alexandra walked = 240ft
z + 2*z = 240ft
3*z = 240ft
z = 240ft/3 = 80ft
They will meet when Wade walks 80ft.
