Question

find an equation of variation in which y varies inversely as x and the following is true.

1.) y=22, when x=4
2.) y=8, when x=11

Answer 1

general line equation is y=mx+c

plug in given x,y give 2 equations.
since y varies inversely as x, the m should be a negative number

Answer 2

y=88/x

y=19/x?
