Which equation is not an example of a linear function?
a) y = 9 - 2x
b) y =
6
x
c) y =
x
2
+ 9
eliminate
d) y =
5
6
x - 8

y =  

6

x

is not a linear relationship. Linear relationships can be written in the form of y = mx + b, and will form a straight line if graphed on the coordinate plane. The equation y =  

6

x

is an inverse variation. The equation for this relationship is y = k/x, and its graph will be a curve.

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

12.5 feet
