Question
Draw a graph of each of the following equations: y = `(5)/(2) xx + (2)/(5)`
Solution
y = `(5)/(2) xx + (2)/(5)`
When x = 1, y = `(5)/(2)(1) + (2)/(5)` = 2.9
When x = 0, y = `(5)/(2)(0) + (2)/(5)` = 0.4
When x = 2, y = `(5)/(2)(2) + (2)/(5)` = 5.4
| x | 1 | 0 | 2 |
| y | 2.9 | 0.4 | 5.4 |
Plotting the points (1, 2, 9), (0, 0.4) and (2, 5.4), we get a line AB as shown in the figure.
