2y - 4x = -12
Algebraically rearrange to
2y = 4x - 12
Divide both sides by '2'
y = 2x - 6
So at the 'y' intercept, x = 0
Substituting x = 0
We have y = 2(0) - 6
Anything multiplied '0' is equal; to '0'
Hence
y = 0 - 6
y = -6 is the value of the y-intercept.

It shows the relationship of y in terms of x. [y = (yIntercept) + ((slope)*(x))] [slope = (y2 - y1)/(x2 - x1)]
y = 12. It's the transitive property. y = 12 = 3x.
