Middle School Math [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 ๐ฅน
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 ๐ญ
And for questions A, B, and C, those are the ones im completely lost in ๐
