Draw the graphs of the equations 5x - y = 5 and 3x - y = 3. Determine the co-ordinates of the vertices of the triangle formed by these lines and the y axis.
5x - y = 5 Or,
y = 5x - 5
The solution table will be as follows.
x | 0 | 1 | 2 |
y | -5 | 0 | 5 |
3x - y = 3 or, y = 3x – 3 | |||
The solution table will be as follows. | |||
x | 0 | 1 | 2 |
y | -3 | 0 | 3 |
The graphical representation of these lines will be as follows.
It can be observed that the required triangle is ΔABC formed by these lines and y-axis. The coordinates of vertices are A (1, 0), B (0, - 3), C (0, - 5).
