I believe the answer is the second one {starts with (2,-1)}.
To be considered a function, the input which is the x value can only have one output which is the y value. The others have at least one input with multiple outputs.

Amery drives 50 miles in one hour. How many miles does he drive in 2.25 hours?

slavikrds [6]

So if he drives 50 miles in 1 hour, then he must drive 100 miles in 2 hours. 0.25 is another way of writing 1/4, and to find 1/4 you divide by 4, so 50 ÷ 4 = 12.5 miles. Then you can add this to 100 and get your answer as 112.5 miles.
If you have a calculator, or if you're allowed a calculator, then a simpler way is to just do 2.25 × 50 = 112.5
Hope this helps!

Ivan biked 1 whole 2/3 on Monday, 2 wholes 1/3 hours on Tuesday, and 2 wholes 2/3 on Wednesday. What is the total number of hour

GenaCL600 [577]

$1 \frac{2}{3} + 2 \frac{1}{3} + 2 \frac{2}{3} =$

$\frac{3*1+2}{3} + \frac{3*2+1}{3} + \frac{3*2+2}{3} =$

$\frac{3+2}{3} + \frac{6+1}{3} + \frac{6+2}{3} =$

$\frac{5}{3} + \frac{7}{3} + \frac{8}{3} =$

$= \frac{20}{3} h$

In hours:

20 |_3
(2)....6hs
x60'
------
120' |_3
(0)....40'

Answer:
6hs40min

or

 $\frac{20}{3} hs = \frac{20}{3} *60' = \frac{1200}{3} = 400'$

400' = 6*60' = 360' + 40' = 400' (True)
Until

6hs40min
