What is the y-intercept of the line? y + 6x - 4y-intercept = ?

Slope intercept form is always y=mx+b where your m is your slope and your b is your y-intercept. Knowing this we first need to put your equation into slope intercept form. to do this all we have to do is subtract everything except why across an equal sign to get y=-6x+4. Now all you have to do is figure out what the 'b' is to know that the y-intercept is 4
