Let the speed of the current be x and the speed of the canoe in still water be y, then

Adding the two equations, we have:

From any of the equations, we have that x = 2
Therefore, the speed of the current is 2 miles per hour while the speed of the canoe in still water is 5 miles per hour.
Answer:
yes
Step-by-step explanation:
The graph of a proportional relationship is a straightline that passes through the origin (0,0).
The only graph with that feature is the option c., so that is the answer.
The other graphs ar linear relationships because the are straighlines that to not pass through the origin.
Answer: the option c.
Answer:
B
Step-by-step explanation:
Because there are 2 different y values for the x value of 5. All x values can only have 1 y value.
For B, there are y points on the x value of 5, so this fails the vertical line test, and is therefore not a function
