which of the following statements are true about the function y = 3x?
the function is a direct variation.
the function goes through the origin.
the constant of variation is .
y is 6, when x is 2.

i and ii
i and iv
i, ii, iii, and iv
i, ii, and iv

I do Monarch/Lifepac and the answer is I, II, IV. Hope this helps!

answer: add the !

step-by-step explanation: then we will answer

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
