What is the x-intercept of the line with this equation −2x+12y=18 ?

Question

dumbcow · Answer

The line crosses the x-axis when y= 0

To find x-intercept, plug in y = 0 and solve for x value

So would i have to multiply the 12 by 0 to get y so far? i've never done this before at all so im clueless haha

dumbcow · Answer

yes you replace "y" with 0

---> -2x + 12(0) = 18

ritoking · Answer

crap i messed up the equation, the 12 is supposed to be 1/2y

dumbcow · Answer

thats ok, either way you multiply it by 0

ritoking · Answer

alrighty, so what do i do for the next step? I know that the equation is now -2x + 0y = 18, but you can't add up two numbers with different letters.

dumbcow · Answer

well 0*anything = 0  right?
the y variable goes away, use algebra to solve for x
---> -2x = 18

ritoking · Answer

would the answer possibly be -9?

dumbcow · Answer

yes correct, 18/-2 = -9

Make sure you write the answer as a point ----> x-intercept is (-9,0)
