Question

Draw a graph of each of the following equations: y = `(5)/(2) xx + (2)/(5)`

Answer 1

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.
