6x-9y=18
The x-intercept is the y value when x=0
What does 6x-9y = 18 reduce to when x=0? What does y equal?
The y-intercept is the x value when y=0
What does 6x-9y = 18 reduce to when y=0. What does x equal?

"x intercept" means the point where the line crosses the x axis, meaning that y = 0. Thus, simply set y = 0 in the equation, leaving this:
6x = 18
solve for x
The process for the y intercept is the same, but you'll put in 0 for x, and then solve for y
Make a graph to see how it all works

As for the bottom 0,-2 top, and 6,2 top right.
Mark H.
That is not correct. The y intercept is at (0,-2), and the x intercept is at (3,0)

In order to find the x and y intercepts, you need your equation in standard form, like you have it above. (AX+BY=C) 1. Finding the X Intercept a. Forget about BY, now you have AX=C, which in this case is 6x = 18 b. Solve for x, divide both sides by 6. c. x = 3, this is your x-intercept. 2. Finding the Y Intercept. a. Forget about AX, now you have BY=C, which in this case is 9y=18 b. Solve for x, divide both sides by 9 c. y = 2, this is your y-intercept10/30/19
