Answer 1

Which statement best explains if the graph correctly represents the proportional relationship y = 3.5x?
A graph of a coordinate plane is shown. Points are graphed at 1 comma 3.5 and 2 comma 7. The points are joined by a line.

No, the points shown on the line would not be part of y = 3.5x
No, proportions cannot be represented on a graph
Yes, the points shown on the line would be part of y = 3.5x
Yes, all proportions can be shown on the graph of this line

Answer 2

I don't understand this question. The answer is either C or D

Answer 3

ok i can tag somone else thats maybe can understand @Michele_Laino

Answer 4

Answer 5

I think the answer would be C, as not all "proportions" can be shown on the graph of the line.
When two things are in proportion, it means that they fit the relationship y = kx, where k is some number. So, y = 3.5x does show a proportional relationship but it doesn't show ALL proportional relationships.

Answer 6

if we replace \(x=1\) into the formula: \(y=3.5\;x\) what value of \(y\) do you get?

Answer 7

3.5

Answer 8

correct! So the point \(1, 3.5\) is part of \(y=3.5x\)
Now, please do the same, namely replace \(x=2\) into the formula \(y=3.5x\), what value of \(y\) do you get?

Answer 9

it will be C

Answer 10

correct!

ok i have two more questions only

Answer 12

ok!
