Question from Natakie, a student: Find the coordinate of the vertices of a triangle whose sides lie on the following three lines. |
Natakie,
Each vertex is at the intersection of two of the lines so take two of the lines, say 2x+5y-16=0 and 4x-3y-6=0, and solve for x and y. These are then the coordinates of one of the vertices. Then choose another pair of lines and solve for x and y to find a second vertex. Finally take the last pair of lines and repeat to find the third vertex.
