Answer 2

first, i would put the equation into y-intercept form (y = mx+b).

Answer 3

Thanks <3

Answer 4

wait, what? haha the first one?

Answer 6

the equation. i'd isolate the y variable in order to make it easier to graph.

Answer 7

Okay :) sorry, i dont really know how to do this stuff haha

Answer 8

haha no it's fine. i go to connections academy and the math classes are hard. okay, do you understand how to isolate y?

Answer 9

yeah they are...expecially when they jump me a class because they think im ready....you put a 0, right?

Answer 10

y=1.6 right?

Answer 11

gosh i can imagine. and not exactly. subtract x from each side and then divide by -3 on each side.

Answer 12

ohhh okay

Answer 13

Im not sure how to divide the 3...

Answer 14

Do i leave it as a fraction?

Answer 15

yup. \[y \le \frac{ 1 }{ 3 }x - \frac{ 5 }{ 3 }\]

Answer 16

okay, then what

Answer 17

oops, but flip the inequality sign to a greater than or equal too since we divided by a negative.

Answer 18

okay :)

Answer 19

with y-intercept form, y=mx+b, b is the number you start with on the y axis. m is your slope. so place a dot on -5/3 and go up one, to the right three and place a dot, and so on for three or four dots.

Answer 20

with that information, we can eliminate two of your choices.

Answer 21

so we can take out a, c?

Answer 22

nope, those are the ones we leave in.

Answer 23

Oh....but i thought i go over negative and up 3?

Answer 24

1/3 was positive. -1x / -3 = 1/3x

Answer 25

Okay i see now sorry

Answer 26

it's fine! okay, do you know how to see which way to shade?

Answer 27

You shade up because its positive? haha

Answer 28

you do shade up haha but pick a coordinate on the graph that doesn't go through your line. (0,0) for example. plug those x and y values into your equation. if your equation is true, shade towards the point you picked, if your equation is false, shade away from the point you picked.

Answer 29

OHHH hahaha i am so lost sometimes!!!

Answer 30

What is the graph of the inequality?

–4y ≥ 8x – 2
i do the same with this?

Answer 31

no, online math is really hard because you're teaching it to yourself basically. do you understand the shading portion?

Answer 32

Yes i think i do :)

Answer 33

and yes. put it into y=mx+b, and shade away haha q:

Answer 34

HAhaha, thanks for your time really helpful!

Answer 35

anytime!
