Please help me, I have a test tomorrow! Attachment bellow:

1. A    2. B

Step-by-step explanation:

Whatever happens to x must also happen to y.

For the first question, x is doubled, which means that the value of y is also doubled.

For the second question, if the value of x triples, then the value of y triples as well, which means that it would be multiplied by 3.

We can check to see if these two answers are true by inputting values into the equations.

For the first equation, let's use the example x = 2

y = 5(2)

y = 10

If the value if x doubled, it would become x = 4

y = 5(4)

y = 20

As you can see, when the value of x doubled from 2 to 4, the value of y also doubled from 10 to 20.

You can do something similar for the other equation.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
