What is the y intercept of the line -9x+3y=18

Answers

y = 6

hope this helps

Answer: (0, 6)

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Question is −9x + 3y = 18

Our first step would be is to find y which will be done by 3y = 18.

Part 1

Step 1: Enter y equation.

3y = 18

Step 2:Simplify.

y = 6

Now that we have our y, we need to find our X. We can do this by plugging in y, which is 6 into the equation to find X.

Part 2

Step 1: Enter the X equation by plugging in y.

−9x + 3(6) + 18

Step 2:Simplify.

−9x + 18 = 18

Step 3:Simplify.

−9x = 18 − 18

Step 4:Simplify.

(-9x)/(-9)  = (0)/(-9)

Step 5: Simplify.

x = 0

Because 0 is our X coordinate and 6 is our Y coordinate, we will need to have the X and Y coordinates in parentheses, So (x, y) would be (0, 6). And there you go we have the answer. Good luck!
