3x=y y=9 Solve for x.

x=3

Step-by-step explanation:

3x=y y=9

fill y in with 9

3x=9

÷3  ÷3

x=3

x = 3

Step-by-step explanation:

3x = y

y = 9

Put y as 9 into the first equation and solve for x.

3x = (9)

Divide both sides by 3.

x = 9/3

x = 3

it's

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.
