4. If f(x) varies directly with x, and f(x) = 45 when x = 9,
find the value of f(x) when x = 3.

5. Which does not show a direct variation between x and y?
Y=4/x
Y=0.5x
Y=7x
7=x/9
3. What is the direct variation equation if f(x) varies
directly with x and f(x) = –18 when x = 3?
f(x) = -1/6 x
f(x) = –3x
f(x) = –6x
f(x) = –15x
