Question

The slope of diagonal AB is_______ , and its equation is_______ .

Answer 1

Did they provide you with the coordinates of a and b?

Answer 2

No they didn't

Answer 3

Alright then I guess this questions theoretical. In that case, what is the equation of a line?

Answer 4

But looking at the graph it looks like a is (-2,-2) and. B is (2,-2)

Answer 5

OKay so have you given us the diagram correctly is it like

Answer 6

Well it may look like it's at those points but we're unsure of it and that may determine an incorrect answer.

Answer 7

Yeah well it is a horizontal line and horizontal line always have gradient 0

Answer 8

now we know it is y = c
but to find it out we actually need atleast one correct coordinate that lies on that line

Answer 9

I'm now on my phone and if I could send a picture of the graph I would but I don't know how

Answer 10

Okay well assuming it is (-2, -2) and (2, -2) we have two coordinate points. So first let me ask you, what is the point-slop equation? Do you know what it is?

Answer 11

slope*

Answer 12

0?

Answer 13

Just tell us any one point

Answer 14

I think one point is (-2,-2)

Answer 15

Well, no. Not 0. It's an equation.

Answer 16

I'm beyond lost now

Answer 17

She is right slope is 0

Answer 18

if its a horizontal line

Answer 19

Okay so we have one point as (-2,-2)
y = c
-2 = c
y = -2

Answer 20

They want me to find the slope of ab

Answer 21

slope is 0

Answer 22

Okay assuming it is horizontal (didnt look that way from first graph) then yes slope is 0.

Answer 23

yes so just pick a point (-2,-2)
y = mx+c
y = 0x+c
y = c
Input a y coordinate
-2 = c
which gives us the constant
y = -2

Answer 24

Got it?

Answer 25

I think so

Answer 26

You should probably be guiding her through it. Not just giving it out like that.

Answer 27

@jtug6 I did guide her out. Now I wont be explaining how to add or subtract. Whenver a new thought arose I explained it to her. And then at last I confirmed by asking if she has gotten.

Answer 28
