Find X intercept for 3x-6y=-18

x-intercept is when y=0 (because the x-axis is the line "y=0"). So just substitute 0 for y, and solve for x:
3x - 6y = -18
3x - 6*0 = -18
3x = -18
x = -6

The x-intercept is where does this line cross the x axis (in other words when y = 0)
so substitute in y = 0 into your eqn and solve for the x intercept
3x -6(0) = -18
3x = -18
x = -6
so the x intercept is (-6,0)

3x-6y=-18
to find x-intercept,put y=0
3x=-18
x=-6 interceptreQd. answer

substitue in 0 for y
so, 3x=-18
x=-6
Hope that helps!

It's -6, isn't it?
