ANSWER
The equation is
EXPLANATION
Let the equation be
where
is the slope of the line.
We substitute this value to obtain,
Since the line passes through
we can use this point to determine the value of c.
We substitute this point to obtain,
Our equation now becomes
We can write this in standard form as
9:4:5.....added together = 18
9/18 (72) = 648/18 = 36
4/18 (72) = 288/18 = 16
5/18 (72) = 360/18 = 20
so we have 36:16:20
Firstly make the f(x) = x and x = y:
x = y^2
Then solve for y:
√x = y
