Question

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

Answer 1

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

Answer 2

add 4x to both sides then devide by 2

Answer 3

2y = -12 + 4x
2y/2 = -12/2 +4x/2
y = -6 + 2x

I'm so confused

Answer 4

or would y = -6?

Answer 5

correct

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

Good.

Answer 11

Thank you very much, all of you.

Answer 12

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.
