Question

how would you graph |x| + |y| = 1? And why is it not a function?

Answer 1

do you know what makes a graph a function?

Answer 2

It's not a function because it isn't. Vertical line test?

For x>0 and y > 0 (1st Quadrant), this is x + y = 1
For x<0 and y > 0 (2md Quadrant), this is -x + y = 1
For x<0 and y < 0 (3rd Quadrant), this is -x - y = 1
You do the last one - Quadrant 4.

Graph the four lines and see what gives!

Answer 3

what he said is exactly what I was going to say haha

Answer 4

and don't forget about your absolute value signs

Answer 5

you got this or no? it is not nearly as hard as it looks

Answer 6

Quadrant 4: x>0 y<0 x - y =1
I got it! thanks everyone:)
