What is the y-coordinate of the y-intercept of the linear equation 2x - 3y = 12?
Plz help I don't understand how to do this can you show me step by step plz, sorry ;-;

easiest way:
for the y-intercept, let x = 0 , (can be done mentally)
so -3y=12 ----- > y = -4
You are probably using the equation in the form
y = mx +b, where b is the y-intercept, so change your given equation to that form
2x - 3y = 12
-3y = -2x + 12
divide by -3
y = (2/3)x - 4 , what do you see instead of b ?
