Is this y-intercept correct?

Question

2x - 4y = 1


y-intercept = - 1/4 right?

Answer 1

Yes, that is correct.

y-intercept is the value of y when x is zero. So plug in x=0 and solve for y and you get -1/4.

Answer 2

x-intercept: (2, 0), y-intercept: (0, ?4), i imagine the third answer is nice. Please "every person" enable me understand if I have the incorrect answer, or proper answer. i want to be a instructor and not in any respect constructive if that is incorrect or proper. one project that facilitates me is to maintain in mind that each and each and every time there's a factor on a graph that's written in this formate (X,Y) no count number what any graph factor is; that's continually witten in (X,Y) like the alphabet X is first and Y nex. to determine out the answer to this question that is what I did to discover the intercept for X we could make Y 0 - so we already understand that is area of the answer (X, 0) to discover the intercept for Y we've make X 0 - so we already understand this area (0, X) remember that area in case you do not comprehend some thing else - that's continually - continually (x,y) and understand even as requested for the X that has to 0, and requested for the Y then X ought to be 0. in an attempt to understand the intercept for X: take the equation and make Y 0 For the x-intercept come to a call for that answer you may make Y 0 contained in the equation 2X-Y=4. So 2X-0 = 4. which means X ought to be 2 ( 2 higher through 2) equals 4 So the x intercept will be (2 for the X, and we already made Y 0). So (2,0) same project for Y you're taking the equation and make the X 0 - and keep in mind that X if the first style contained in the (x,y) expression. So x is already (0, and are available to a call for Y) i want to develop right into a instructor. i wish that is nice. i want to teach Algebra, yet do not understand what grade.. Please every person answering this question enable me understand if I defined it nicely, if I have the incorrect answer. What grade replaced into the question requested in? thanks in actual actuality -

Answer 3

You have the equation: 2x - 4y = 1

so you have to put this into the form of y = mx + b (where b is the y-intercept)

so, 2x - 4y = 1
2x - 1 = 4y
therefore: y = (1/2)x - (1/4)

so the y-intercept is -1/4.
you're right!!

Answer 4

1/4

Answer 5

no
y=mx+b
b is the y intercept/constant
the y intercept is 1

the y intercept is different than solving for y

2x-4y=1
-2x -2x
-4y=-2x+1
-4y = -2(0)=1
-4y = 1
y = - 1/4

the y intercept is where y meets at the 0 point of x it is not the same as the y point in an ordered pair or (x,y)

Answer 6

That's right!
But my teacher makes us write it like (0, -1/4), so you might want to se if you have to do that

Answer 7

yep

Answer 8

You are wrong crct2004 !

Answer 9

you got it
