Add 6+7+9, which gives 22.
Divide 44 by 22, which is 2.
Multiply the ratio by 2:
(6 : 7 : 9) * 2 = 12 : 14 : 18
The lengths of the sides are 12cm, 14cm, 18cm.
A function will not have any repeating x values....all the x values must be different....now it can have repeating y values, just not the x ones.
so ur function is { (3,-1),(7,1),(-6,-1),(9,1),(2,-1)}.....because all the x values are different
