Which of the following equations
represents a direct proportional
relationship?
c
a y = 4x
pc y = 2
b y = x -1 0 y=x+23
.x
b
in
y
1
x
-1
d
y = x +

All of them.

Step-by-step explanation:

Although it was hard to understand the equation being posted, but as we see that among almost all of them , there is no equation in which the x is in the denominator or x in in the denominator. Hence there is no inverse relationship seen in any of the equation. Thus in all of them y variables are directly proportional to respective x variables .

Example:

y=2x-3

y=-x+7

They are directly proportional.

y=1/x + 3

xy=4

They are inversely proportional
