Tell whether x and y show direct variation.
xy=5
Answers
So here you have xy = 5.
Divide both sides by x, and you have y = 5/x.
So it is not direct variable, it is inverse variation.
indirect variation is a=xy where when x goes down y goes up so less say a=2 then if x=2 then y=1 if x=1 then y=2
for number 9. it shows direct variation because when x goes up, y also must go up

The sum will have an x-term sumtimes ... whenever
the x-terms alone don't add up to zero.
Examples:
-- Two linear expressions:
y + x
and
y + 2x
The sum of the x-terms alone is (x + 2x) = 3x .
So the sum of the expressions has an x-term.
(y + x) + (y + 2x) = 2y + 3x .
_______________________________
Two different linear expressions:
y + 3x
and
y - 3x
The sum of the x-terms alone is (3x - 3x) = zero.
So the sum of the expressions doesn't have an x-term.
(y + 3x) + (y - 3x) = 2y .
