Answer: 2.
Step-by-step explanation:
You can find the slope between two points by using the "rise-over-run" method.
This method essentially calculates the slope as the quotient of the vertical span and horizontal span of the two points.
You can find it through this formula:
To find the slope, use two points, (x1, y1) and (x2 and y2).
For the points given, I will replace those values in the formula with (-33, -27) and (-32, -25).
The slope of the line is 2.
Answer:
(a)The amount of fuel in dollars = $1.62
(b)The rate equivalent to in U.S. dollars per gallon = $ 1.45
Step-by-step explanation:
Reid will be driving through Spain this summer. He did some research and knows that the average price of gas in Spain is approximately 1.12 euros per liter.
1 USD = 0.69 euros
We have to find the money that we should pay in order to get the same amount of fuel.
1 euro =
1 euro = $1.45
So 1.12 euros = 1.121.45 = $1.62
(a)The amount of fuel in dollars = $1.62
(b)The rate equivalent to in U.S. dollars per gallon = $ 1.45
