Question

What is the y-intercept of the equation 3y + 2x = 12?
A.(0,4)
B.(4,0)
C.(4,4)
D.(0,0)

Answer 1

Look :
If we want to have a standard form should be have y alone .
So have this : y=mx+d
So y is alone means nothing is before or after that ... So we have3y + 2x = 12= 3y=-2x+12
But 3 is extra .. So delete it from this way ...:(Divided on 3) y=-2x/2+4
So y-intercept is 4 .!
Got it ?:)

Answer 2

ok so its b.(4,0)?

Answer 3

@sione

Answer 4

We have :
In the b :
3*4+0=12
So it s right :)
Yea !

Answer 5

ok thank you

Answer 6

to find the y intercept, you could just sub in 0 for x
3y + 2x = 12
3y + 2(0) = 12
3y = 12
y = 4

no....y intercept is (0,4) not (4,0) because your solution set is (x,y)
answer is A

Answer 7

thank you!
