Question

Find the y-intercept of x-2y=4 and some of my answers are (-2,0) , (0,-2), (0,4) ,(4,0)

Answer 1

the y intercept would be (0,-2)

Answer 2

To find the y intercept set x for 0
To find for x intercepts set y for 0

So, x-2y=4 to find y set x for 0

0 -2y = 4

-2y is the y intercept or (0,-2)

Answer 3

Let's try (-2, 0). Plug in the numbers in that equation.
x - 2y =4
Which would be..
-2 - 2(0) = 4
= -2 - 0 = 4
= -2

How about (0, -2). Again plug in the numbers into the equation.
x - 2y = 4
That is..
0 - -2(-2) = 4
= 0 - 4 = 4
= -4 = 4...
Um.... I tried my best on that. I know it ISSS (0, -2). Maybe.. Switch the numbers? I don't know.

I am not very good at explaining things.
