@AZ

AZ:

so our original blue graph is f(x) our new red graph is 1/3 f(x) that means whatever the y-value is, we divide by 3 so on the original blue graph, when x = 1, what is the y-value? then divide that y-value by 3 and that will be the y-value for the new red line when x = 1

AZ:

do the same thing for when x = 0 and when x = 2 and x = 3

iuytyuioiuytyuiop:

y value is 1

AZ:

yes, so that's for when x = 1 so move one of your red dots to (1, 1) now when x = 0, what is the y-value on the blue line? then divide that by 3 and that's the new y-value for the red line when x = 0

iuytyuioiuytyuiop:

the y value is 0?

AZ:

yes now what about when x = 2 what will be the y-value for our new red line

az?

iuytyuioiuytyuiop:

az

iuytyuioiuytyuiop:

az?

AZ:

uh why'd you move two of the red dots to (0, 0) only move one of them

iuytyuioiuytyuiop:

x=3 the y value is 0?

AZ:

yes and what about when x = 2

iuytyuioiuytyuiop:

6

AZ:

and divide by 3 so that way you get the new y-value

iuytyuioiuytyuiop:

2

AZ:

yes so plot that (2, 2)
