which equations show direct variation between x and y?

choose all answers that are correct.

a. 3x = y

b. y = 4.2/x

c. y/x = 6

d. y =0.5x + 9

yo answer should be 6 if im not mistaken

step-by-step explanation:

1. minimum

2. 6400

3. eight

hope this !

answer: the answer is ann

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
