#

lowk help me i have a test tomorrow

#

guys please

oak rain Apr 20, 2026, 9:34 PM

#

i haven't seen geometry questions in years so idrk what it means when it says the gradient of L is sqrt(3) but from what it looks like, you can just solve for f

#

for the first question

delicate quarry Apr 20, 2026, 9:34 PM

#

i tried to solvefor it

#

but i get number bihger than -4

oak rain Apr 20, 2026, 9:35 PM

#

wut 🥀

#

k w8

delicate quarry Apr 20, 2026, 9:36 PM

#

nvm i looked at the wrong point

#

WHAT FING LINE PASSES THRU x=-2

#

it they mean point d ITS X COORDINATE JS NOT -2

oak rain Apr 20, 2026, 9:39 PM

#

i got (4,0) wtf

#

lmfao

delicate quarry Apr 20, 2026, 9:39 PM

#

whoever made this shit of a problem knows no basic math

oak rain Apr 20, 2026, 9:39 PM

#

#

welp 🥀

delicate quarry Apr 20, 2026, 9:41 PM

#

oak rain

what are u calculating

#

point D?

#

@arctic pulsar

#

yo

#

the hell

#

MANNN X COORDINATE OF D IS NOT FING -2

#

its all in positive

#

im getting angry

oak rain Apr 20, 2026, 9:44 PM

#

delicate quarry point D?

yh tried to

delicate quarry Apr 20, 2026, 9:44 PM

#

well x coordinate is already given

#

u see

#

-2

#

but it cant be -2

oak rain Apr 20, 2026, 9:44 PM

#

yea ik so uh 💀

#

doesn't make sense to me

delicate quarry Apr 20, 2026, 9:45 PM

#

see O is (0,0)

#

and d is in positive for x and y too

#

and it isnt even a diagram

oak rain Apr 20, 2026, 10:21 PM

#

ok so the gradient it just means slope

#

slope = rise/run = sqrt(3)

#

point (-2, f) is a random point on line L

#

find point D use slope of L to find point (-2, f)

#

@arctic pulsar

#

#

for 2nd problem, translation vector means the whole circle gets moved by the direction and distance of the vector aka the circle gets moved by the x and y of the vector

#

it's x and y are 0 and -2 respectively

#

so x^2 + y^2 = 25 changes to x^2 + (y-5)^2 = 25

#

remember the actual formula for a circle
(x - x0)^2 + (y - y0)^2 = radius^2

#

oak rain ok so the gradient it just means slope

u couldve asked me that😭

oak rain Apr 20, 2026, 10:41 PM

#

delicate quarry u couldve asked me that😭

mbxd

oak rain Apr 20, 2026, 10:41 PM

#

oak rain remember the actual formula for a circle (x - x0)^2 + (y - y0)^2 = radius^2

so x and y are just x and y but x0 is the x for the center of the circle and y0 is the y for the center of the circle

delicate quarry Apr 20, 2026, 10:41 PM

#

oak rain

d has 0,4 coordinates?

#

hows that possible

#

both x and y are >0

oak rain Apr 20, 2026, 10:43 PM

#

LMAO

#

i see my mistake there

#

i said (1/4)(16,-8) = (16,-8)

#

ok correct that and the rest of the steps should be fine

delicate quarry Apr 20, 2026, 10:46 PM

#

yeah u didnt divide y by 4?

oak rain Apr 20, 2026, 11:28 PM

#

yep

thanks guys

#

i definitely fucked up the L one but must hsve got some marks
