How to solve this question

Mathematics

Direct variation can be written as a proportion. Therefore, we can write:

\frac{8}{4}= \frac{y}{5}
Cross multiply to get:
4y=40
Divide by 4 on both sides to get that y=10.

Help please! I already know the answer isn't -2, -1 so I need help figuring out the rest!
Lelu [443]

the function is increasing from x = 0 to x = 1

when x = 0, y = 2

when x = 1, y = 8

this shows an increase of +6, so we know this statement is true

we can see the rest are false simply because they state a decrease when there is an increase. this question is only confusing because we ask you about the increase and decrease in the function, when really its the same thing as asking about an increase or decrease in the y variable.

in other words, all youre looking for is the variation of the value of the y variable that is attached to the specific x variables.

hope this helps!!
