How to do question 3 part c? To save you the time, k = -3.

#

I don't know.

winged cosmos Jan 13, 2025, 10:28 PM

#

Okay so y =mx and x = x

#

olive flower Jan 13, 2025, 10:30 PM

#

Okay

winged cosmos Jan 13, 2025, 10:30 PM

#

Do it like this

olive flower Jan 13, 2025, 10:30 PM

#

olive flower Okay

And then what

winged cosmos Jan 13, 2025, 10:30 PM

#

Multiply the matrix

#

Wait do you need to label the x or is it just the same?

olive flower Jan 13, 2025, 10:31 PM

#

I think so no?

#

Idk man

winged cosmos Jan 13, 2025, 10:31 PM

#

I used the wrong matrix

#

You solve them simultaneously

#

I think on the lhs you do x2

#

Is matrix T correct?

#

Ah I see m is equal to 1 or -1 as it doesn’t affect the equation

#

Bro I have no idea

winged cosmos Jan 13, 2025, 10:34 PM

#

No you did to right

#

It

#

For equation 2 if m is negative 1 the equation is the same

#

And it’s it’s 1 it’s the same

#

So m is 1 and -1

Hows my man in y9 helping 😭

winged cosmos Jan 13, 2025, 10:39 PM

Just a legend

#

I did it in year 8 in china

olive flower How to do question 3 part c? To save you the time, k = -3.

This question doesn’t even make sense

#

It’s an enlargement any real m yields an invariant line
