Question
Solve the following simultaneous equations by graphical method.
✓
Answer
$x-y=1$
From the equation $x-y=1$we find the corresponding values of y.
Explanation :
When $x=0, y=-1$.
When $y=0, x=1$.
When $x=3, y=2$.
When $y=-3, x=-2$.
Explanation :
When $x=2, y=3$.
When $y=8, x=5$.
When $y=-2, x=-1$.
When $x=-4, y=-7$.
From the equation $x-y=1$we find the corresponding values of y.
| x | 0 | 1 | 3 | -2 |
| y | -1 | 0 | 2 | -3 |
| (x, y) | (0, -1) | (1, 0) | (3, 2) | (-2, -3) |
When $x=0, y=-1$.
When $y=0, x=1$.
When $x=3, y=2$.
When $y=-3, x=-2$.
| x | 2 | 5 | -1 | -4 |
| y | 3 | 8 | -2 | -7 |
| (x, y) | (2, 3) | (5, 8) | (-1, -2) | (-4, -7) |
When $x=2, y=3$.
When $y=8, x=5$.
When $y=-2, x=-1$.
When $x=-4, y=-7$.
