@lowkey

dude:

Okay, so first you want to label the points, do you know how to do that?

bill533:

no i knew at one time

dude:

So basically you look at the point and look at the numbers directly above/below it and to the left/right In this case it was below and to the right, this points would be (-2,2)4MLORhX4QYmi8AS-Ibnf3A.png

bill533:

oh ok

dude:

Can you do it for the other 3 points?

dude:

Or do you want me to walk you through it

bill533:

nah let me try

bill533:

(2, 2) (6, 5) i think i might be wrong with these two

dude:

(2,2) is right (6,5) check again, look down at where the x is and then to the left or right depending on where the point is

bill533:

(5, 2) (5, -2)

dude:

Right

dude:

So we have (-2,2) (2,2) (-2,5) (2,5) Now multiply the points by 2 ex. (2,2) => (4,4)

bill533:

(-2,2) = -4 (2,2) = 4 (-2,5) = -10 (2,5) = 10

dude:

They're points so remember you are doing 2 digits per point (-2,2) = (-4,4) (2,2) = (4,4) (-2,5) = (-4,10) (2,5) = (4,10) Okay so now we want to plot the new points

dude:

Do you know how to plot (-4,4) (4,4) (-4,10) (4,10)

bill533:

not exactly

dude:

Example for the first point dC3iqto4RAi3pJBbt8kUOA.png

dude:

Look at the first number, move to where that point is Look at the second number, now go up that number of times and that is your point

bill533:

i put it on desmos and this is what i got

dude:

Right

bill533:

but i don't know how to line those points on desmos

dude:

How to connect them?

bill533:

yes

dude:

I know there is a more easier way to do this but https://www.desmos.com/calculator/a7zelsxfik The purple rectangle is the dilated one

bill533:

oh ok and the black one is the problem we're solving ?

dude:

The black one was the original one, just for reference, not the answer

bill533:
