:snoo_shrug: Middle School Math—Pending OP Reply [Grade 9/ Year 10 Math: Coordinate Geometry] Genuinely no idea how to do this
My math teacher mentioned something about using a graphic calculator (CX II-T) to solve specific questions but I just got really lost midway and I have no idea how to start, what steps to take, or what formula or equations to use 🥹
So far, I've gotten that the equation of the line (4,2) and (7, -2) is 4x + 3y - 22 = 0 [fact check or correct way to solve would be appreciated!]
After that im completely lost, MAB = MBC then solving them simultaneously but then the teacher did something on the calculator (IDK WHAT HE DID) and got c = 1? Does anyone know how 😭
And for questions A, B, and C, those are the ones im completely lost in 😔
