i need to do this and i don't get it ! i've tried like 100 times! help please!
AB y= -2x + 21 BC y= 1x - 12 CA y=2 a) Choose two of the above equations to form a linear system b) Solve the linear system (substitution method of linear combination method.) c) Show that the point above is on the third line by substituting the coordinates into the equation. thanks :) i'm almost pulling my hair out over this. |
