Question

Find the coordinates of the x-intercept.
-x - 2y = 6

Answer 1

Hmm.. there's probably a better way to do this, but here's how I'd solve it:
First find the y intercept by converting to the y intercept form of a line.
-x - 2y = 6
-2y=x+6
2y=-x-6
y=-1/2x-3
So we know that the y-intercept is -3.
Now to go up once, we go over 2 to the left.
So to go up 3, (to find the x-intercept) we need to go over 6 to the left.
So our x intercept is -6.

Answer 2

Sorry. you want the coordinates of the x intercept.
It would just be (-6, 0) because where it intercepts the x axis y will equal 0.

Answer 3

Another, simpler, way to solve it is the set y = 0.

Answer 4

LOL!
Thanks iPwnBunnies. I didn't even think of that.
