Question

Identify the correct x intercept and y intercept of the equation x - 2y = 8.

x intercept = (8, 0); y intercept = (0, 4)

x intercept = (8, 0); y intercept = (0, -4)

x intercept = (-8, 0); y intercept = (0, -4)

x intercept = (-2, 0); y intercept = (0, 8)

Answer 1

To find the x intercept we make y = 0
x - 2y = 8
x - 2(0) = 8
x = 8
x intercept = (8,0) when y = 0

Do the same to find the y intercept. make x = 0

0 - 2y = 8
-2y = 8

can you finish it?

Answer 2

-2/-2y=8/-2
y=-4
Is that correct??

Answer 3

-8/-2 = 4 so the y intercept is (0,4) when x = 0.

You were right but you forgot to do the negatives.
A negative divided by a negative = positive.

Answer 4

Oh okay, so the 8 was a negative?

Answer 5

Oh wait I might of been wrong lol that is a +8 lol

Answer 6

You are correct. -4 so the y intercept is (0,-4) it is late here and I am getting tired lol

Answer 7

Me too. What time is it there where u live?

Answer 8

11:00 pm

Answer 9

Same time here too

Answer 10

so the answer is the second one down.

Answer 11

Don't forget the medal :-) I do like the shiny :-D

Answer 12

OK Thanks!!

Answer 13

yep, y-intercept is at (0,-4), x-intercept is at (8,0)
