Identifying Inverse and Direct Variation in Equations

What is the first step in identifying equations in inverse variation?

• Checking if the variables are divided

• Checking if the variables are subtracted

• Checking if the variables are multiplied

• Checking if the variables are added

If X increases and Y also increases, what type of variation is this?

• Inverse variation

• Direct variation

• Neither

• Proportional variation

In a direct variation, if X is 1 and Y is 6, what will Y be if X is 2?

• 1

• 6

• 3

• 12

What happens to Y in an inverse variation if X increases?

• Y increases

• Y remains the same

• Y decreases

• Y becomes zero

In an inverse variation, if X is 2 and Y is -1/8, what will Y be if X is 4?

• -1/4

• -1/16

• -1/2

• -1/32

What type of variation is it when the equation includes a plus or minus sign?

• Proportional variation

• Inverse variation

• Direct variation

• Neither

Which of the following is an example of neither direct nor inverse variation?

• Y = 2X

• XY = 1

• Y = X + 3

• Y = 1/X

In the equation Y = MX + B, what type of variation is represented?

• Proportional variation

• Neither

• Inverse variation

• Direct variation

What should you do if you encounter an equation with a plus or minus sign?

• Consider it direct variation

• Consider it neither

• Consider it proportional variation

• Consider it inverse variation

Which of the following is true for direct variation?

• X and Y are subtracted

• X and Y are multiplied

• X and Y are added

• X and Y are divided
