There are some we've learned. idk If it's for this. But theirs E M E, then another one

try to type the equations out with the equation setting thing

curries · Answer

i didn't see it..

DonaldTrumpofQC · Answer

$$\left( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} \right)$$

curries · Answer

oh, thanks

DonaldTrumpofQC · Answer

I'm confused on what the question is asking

curries · Answer

wait let me redo this i slipped up a little..

curries · Answer

bc we're finding out what the coordinates for c is, i suggest replacing the numbers with their respective variables, like x$$x _{a}$$ for example

curries · Answer

i'd also add the midpoint equation into the problem in front of it, like M(xₘ, yₘ) = $$\left( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} \right)$$

curries · Answer

once u get that, plug in your numbers that u DO have into the equation

fixing this, its $$\left( \frac{x_a+x_c}{2}, \frac{y_a+y_c}{2} \right)$$

curries · Answer

after u plug in the m's and a's, show me what u have

DonaldTrumpofQC · Answer

idk what to even do...

DonaldTrumpofQC · Answer

WAIT

curries · Answer

what dont u understand? i can fix some instructions if u need to

DonaldTrumpofQC · Answer

hang on. I'm getting it...

DonaldTrumpofQC · Answer

I'm at 2*3=-1+y
6=-1+y

si- have you figured out how to solve it yet or did you solve it differently than meant to? If you haven't figured it out yet I might be able to help you for future problems like that

i know I was just asking if you know the correct way to solve it now since you didn't before .
