The graph of the function is a straight line passing through points (0, -175) and points (25, 0)
Direct variation is of the form y = kx where k is a constant
So its A
Answer:
You have to find the slope first. Which is y1-y1 divided by x1-x2
Then you find the y-intercept which you take the slope for m like for example if you find the slope, 2, then the equation should be y=2x+b. You take the coordinates on the problem and put them on the y or x on the equation. Then when you find the y-intercept you add it to the equation like for the example that I used above, you have to put the y-intercept on b. So if the y-intercept is 5 then the equation would be y=2x+5.

Convert hours to minutes
----------------------------------------
1 hour 55 mins = 60 + 55 = 115 mins
1 hour 50 mins = 60 + 50 = 110 mins

Speed = 36/h
----------------------------------------
1 hour = 36 km
----------------------------------------
Rewrite 1 hour as 60 mins
----------------------------------------
60 mins = 36 km
----------------------------------------
Find 1 min
----------------------------------------
1 min = 36 ÷ 60
1 min = 0.6 km
----------------------------------------
Find 115 mins
----------------------------------------
1 min = 0.6 km
115 min = 0.6 x 115
115 min = 69km

Speed = 72km/h
----------------------------------------
1 hour = 72 km
----------------------------------------
Write 1 hour as 60 mins
----------------------------------------
60 mins = 72 km
----------------------------------------
Find 1 min
----------------------------------------
1 min = 72 ÷ 60
1 min = 1.2 km
----------------------------------------
Find 110 min
----------------------------------------
1 min = 1.2 km
110 min = 1.2 x 110
110 min = 132 km

Total Distance traveled:
----------------------------------------
69km + 132km = 201km
----------------------------------------
Answer: 201 km
