Answer:
y = -3x + 4
Step-by-step explanation:
3y + 9x = 12
subtract 9x
3y = 12 - 9x
divide by 3 on both sides
y = 4 - 3x
or
y=-3x + 4
Convert standard form equation into y-intercept form
3y +9x=12
3y= 12-9x
Divide both sides by 3 to isolate the y (you can flip the equation if it is easier)
y= -3x+4
hope this helps and have a great day :)
