Question
For the pair of linear equations given below, draw graphs and then state, whether the lines drawn are parallel or perpendicular to each other$.y = x - 3,y = - x + 5$
✓
Answer
To draw the graph of $y = x - 3$ and $y = - x + 5$ follows the steps:
First, prepare a table as below:
Now sketch the graph as shown:
From the graph it can verify that the lines are perpendicular.
First, prepare a table as below:
| $X$ | $- 1$ | $0$ | $1$ |
| $Y = x - 3$ | $- 4$ | $-3$ | $- 2$ |
| $Y = - x + 5$ | $6$ | $5$ | $4$ |
From the graph it can verify that the lines are perpendicular.
