Question
Draw the graph for the equation, given below :$5x + y + 5 = 0$
✓
Answer
$5x + y + 5 = 0$
$\Rightarrow y = - 5x - 5$
When $x = 0;$
$y = - 5 x - 5$
$= - 0 - 5$
$= - 5$
When $x = - 1;$
$y = - 5 \times (- 1) - 5$
$= 5 - 5$
$= 0$
When $x = - 2;$
$y = - 5 \times (- 2) - 5$
$= 10 - 5$
$= 5$
Plotting these points we get the required graph as shown below:
$\Rightarrow y = - 5x - 5$
When $x = 0;$
$y = - 5 x - 5$
$= - 0 - 5$
$= - 5$
When $x = - 1;$
$y = - 5 \times (- 1) - 5$
$= 5 - 5$
$= 0$
When $x = - 2;$
$y = - 5 \times (- 2) - 5$
$= 10 - 5$
$= 5$
| $X$ | $0$ | $- 1$ | $- 2$ |
| $Y$ | $- 5$ | $0$ | $5$ |
