Answer:
B
Step-by-step explanation:
Line crosses y-axis at 2.
Slope = 
For each 1 square the line rises/falls it moves to the right/left 5 squares.
Negative slope lines are downhill left to right.
<em>If the rate is a constant, the relationship is proportional.</em> (The rate is the constant of porportionality.)
_____
For two or more points on the function curve, divide the dependent variable value by the independent one. If you get the same result in every case, the relationship is porportional.
___
<em>Note</em>
For some non-proportional relationships, it is possible to find points on the graph that will pass the above test. If you suspect the relationship is actually not one of proportionality, try more points. Check also to make sure that (0, 0) is on the curve.
Answer:
12 minutes
Step-by-step explanation:
<u>50 miles</u> = <u>10 miles</u> << Equivalent
1 hour = x << fraction
You divide 50 by 5 to get 10,
so to get the number of minutes for 10 miles,
divide 60 by 5.
(1 hour = 60 minutes, 60/5 = 12)
Answer:D
Step-by-step explanation:
You know that the card picked is an 8, so forget the rest of the deck (they are trying to trick you into thinking it is 2 cards out of 52 cards). So there are 4 8's in a deck. 2 are red, 2 are black. You have a 2/4 chance of pulling a red. 2/4 = 1/2
