Find the y-intercept in this linear equation:
2y - 4x = -12

Question

Find the y-intercept in this linear equation:
2y - 4x = -12

anonymous · Answer

change the equation to y=mx+b form then b will  be y intercept

anonymous · Answer

add 4x to both sides then devide by 2

anonymous · Answer

2y = -12 + 4x
2y/2 = -12/2 +4x/2
y = -6 + 2x

I'm so confused

anonymous · Answer

or would y = -6?

zzr0ck3r · Answer

correct

radar · Answer

Just let y=0 and you see that -4x=-12, so the x intercept is 3
       let x=0 and y=-6

anonymous · Answer

So, if they don't give you a "x" it is automatically set to 0?

radar · Answer

If no x is given, then it is a horizontal line where y is a constant.

anonymous · Answer

If i'm finding the x-intercept it would be:
2y - 4x = -12
2(0) -4x = -12
-4x/-4 = -12/-4
x = 3 ?

radar · Answer

Good.

anonymous · Answer

Thank you very much, all of you.

radar · Answer

X intercept, is the point on a line that intercepts the x axis, you let y=0 to find the x intercept, and let x=0 to find the y intercept.
