Question
Draw a graph of each of the following equations: y = `(3)/(5) x - 1`
Solution
y = `(3)/(5) x - 1`
When x = 5, y = `(3)/(5)(5) - 1` = 2
When x = -5, y = `(3)/(5)(-5) - 1` = -4
When x = 10, y = `(3)/(5)(10) - 1` = 5
| x | 5 | -5 | 10 |
| y | 2 | -4 | 5 |
Plotting the points (5, 2), (-5, -4) and (10, 5), we get a line AB as shown in the figure.
