Answer 1

Can you graph the line y=4x-2?

Answer 2

Heres my problem i dont even know how to tell what the points are on the graph and with out that i cant figure out what (x, y) is.

Answer 3

When I look at these graphs I see a white area and a grey area with a bunch of dots. The grey area is meant to represent the part of the plane that satifies the inequality. So the best way to approach this is to get a piece of paper, make
your own graph, and then see which picture resembles your own....

The first step in that process is making a graph of y=4x-2.

Answer 4

Thanks for coming so quick :D

Answer 5

I was in the neighborhood

Answer 6

Oh great

Answer 7

Did you make the graph?

Answer 8

Yeah I got (0, 2)

Answer 9

(0,-2)?

Answer 10

Yeah when you solve what you told me to solve.

Answer 11

wait whoops I got this wrong I just woke up I though < was a = sign sorry xD

Answer 12

WAIT I KNOW IT

Answer 13

(4, -2)

Answer 14

Is that right? Haha sorry

Answer 15

So then it would be D?

Answer 16

Instead of finding a point on the line, we need to draw the whole line. Can you draw a set of axes?

Answer 17

What?

Answer 18

The answers are pictures, so we need to make a picture to see which matches

Answer 19

Okay so how do we do that?

Answer 20

Draw a set of axes(x and y)

Answer 21

Nothing fancy required just a line going sideways and another going up and down.....

Answer 22

I know I was trying to type the numbers but it was being stupid with me

Answer 23

Are you done? Btw I have some more just like 3 if you're williing to help

Answer 24

Nice. We want to draw the line y=4x-2 on this picture. So we need to find the point on the line where x=0.(Paradoxically, this is called the y-intercept.) So what is y when x=0?

Answer 25

1?

Answer 26

y=4x-2, so when x=0, y = 4*0 -2 =-2. So we know the point (0,-2) is on the line.
Put this point on your picture.

Answer 27

Thats what I said. Thanks for explaining it :3 let me put it on a graph one second

Answer 28

Good. Now we want to draw in the rest of the line. Can you find the slope from the equation y=4x-2

Answer 29

Would it be B @fwizbang
