[tex]\text{To find the y intercept, turn the equation into slope intercept form: y=mx+b}\\\\-2y-4x-6=0\\\\\text{Add 4x to both sides}\\\\-2y-6=4x\\\\\text{Add 6 to both sides}\\\\-2y=4x+6\\\\\text{Divide by -2}\\\\y=-2x-3\\\\\text{The y intercept is the "b" value, therefore your y intercept is -3}\\\\\boxed{\text{Answer: -3}}[/tex]
