Question

Need help pls! @ganeshie8

Answer 1

FIrst calculate the slope of the left line

Answer 2

yes ^

Answer 3

can u help me to calculate the slope of the left line @ganeshie8

Answer 4

or @3abf6277

Answer 5

Tell me what point is intersecting the vertical axis on the left line. and then tell me what point is touching the horizontal axis(its between 1 and 2)

Answer 6

3? 1.5? @3abf6277

Answer 7

@3abf6277

Answer 8

well its a point so it would be... (x, y) tell me the point in that form

Answer 9

(0,3) (1.5,0)

Answer 10

@3abf6277

Answer 11

correct. Now what is the equation for the slope between 2 lines? rise / run right?

Answer 12

\[y=\left| mx+n \right|\]

Answer 13

@3abf6277

Answer 14

well no, what is the slope equation between just 2 points?

Answer 15

i'll save you some googling. Its (x2 - x1) / (y2 - y1). the different y's refer to the different y values in the 2 points you have. so for point 1, for example (0,3), 0 would be x1, and 3 would be y1. can you tell me what x2 and y2 would be for the other point?

Answer 16

i messed up its actually (y2 - y1) / (x2 - x1) my bad

Answer 17

\[=\frac{ -3 }{ 1.5 }\]

Answer 18

=-2

Answer 19

indeed!!

Answer 20

so because that is the slope of the left line, and this equation is an absolute value equation. does it look like the slope of the right line is the same but different some way?

Answer 21

yes it look different

Answer 22

does it look mirrored in a way? like flipped across vertically?

Answer 23

it look mirrored in a way

Answer 24

indeed absolute value makes all values coming out of it positive.

Answer 25

try changing the value for m and see what happens to the graph.

Answer 26

use this http://graph.tk/

Answer 27

2?

Answer 28

@3abf6277

Answer 29

2 or -2 does not change direction of the slope of the graph

Answer 30

now for n try adjusting values in the http://graph.tk/ to see what values it would give you to make the right graph

Answer 31

hint: you'll figure out that added or subtracting numbers on the y or the x will affect how the graphs moves,

Answer 33

@3abf6277 has the right idea, @MARC_ :)

Answer 34

But I don't understand... :(
