4+5 and 5+4 because they use the same numbers but just reversed
The two points (0,0) and (4,5) are on the line. The points are marked in blue in the attached image below.
Use the slope formula to get
m = (y2-y1)/(x2-x1)
m = (5-0)/(4-0)
m = 5/4 <----- this is the answer in fraction form
m = 1.25 <----- this is the answer in decimal form
The idea of the slope formula is we're subtracting the y values together, then subtracting the x values together in the same order, finally we divide the two results and reduce if possible to get the fraction form. Use long division or a calculator to find the decimal form of the fraction. In this case, the rise is 5 and the run is 4. Meaning we go up 5 units and over to the left 4 units to go from (0,0) to (4,5).
You are travelling 65 miles in 1 hour, or 60 minutes.
So 65 miles in 60 minutes
And x miles in 22 minutes
We can solve the following for x to get the answer

Hope that helps. :)
Answer:
3
Step-by-step explanation:
5x-22 = -7
5x=15
x = 3
