Question

WILL MEDAL! PLEASE HELP!


Use integer values of x from –3 to 3 to graph the equation.

y = –|x|

Answer 1

@iGreen

Answer 2

y=-|x| will look like the second graph
y=-|x| with x being -3,-2,-1,0,1,2,3 will be a straight line going through (0,-1) (0,-2) and (0,-3) regardless of positive or negative value due to "-|x|"

cant help sorry

Answer 10

:( It's ok thanks for trying

Answer 11

@iGreen

Answer 12

Plug in 1

Answer 13

\(\sf y = -|x|\)

\(\sf y = -|1|\)

Answer 14

Can you simplify it?

Answer 15

um idk I'm really bad at this :(

Answer 16

Okay, the absolute value signs, those lines, make the value inside of it positive..so what's inside the signs?

Answer 17

... a negative sign?

Answer 18

No, the negative sign is outside of it.

Answer 19

oh so nothing is inside the signs?

Answer 20

The signs are "|"

Answer 21

the letter "x"?

Answer 22

Yes..and what did we replace 'x' with?

Answer 23

1

Answer 24

Correct, so is 1 positive or negative?

Answer 25

negative?

Answer 26

No, just the number "1".

Answer 27

oh...

Answer 28

It's positive, so it stays positive.

Answer 29

ok

Answer 30

\(\sf y = -(1)\)

Answer 31

Now multiply -1 to 1, since there is a negative sign OUTSIDE of the absolute value signs.

Answer 32

It would be –1, right?

Answer 33

Yes, that gives us \(\sf y = -1\)

Answer 34

So one of our points is (1, -1), because we plugged in 1 for 'x', and got y = -1.

Answer 35

Which graph has (1, -1) on it?

Answer 36

I think the first one?

Answer 37

No, that's incorrect, the dot on the graph is (1, -1), and it's not located on one of the lines.

Answer 38

The second one, then?

Answer 39

Correct!

Answer 40

YAY!

Answer 41

Thank you SO much! I understand a little better now. I'm sorry for taking so long for me to understand it I'm not the best in this area. THANK YOU!

Answer 42
