Find the Equation

100

Remember:

Input will be "X" and output will be "Y"

What is the equation if I add 6 to the input?

y = x + 6

200

Remember:

Input will be "X" and output will be "Y"

What is the equation if I subtract 13 from the input?

y = x - 13

300

Remember:

Input will be "X" and output will be "Y"

What is the equation if I multiply the input by 8?

y = 8x or y = 8 x (x)

400

Remember:

Input will be "X" and output will be "Y"

What is the equation if I divide the input by 9?

y = x / 9

500

Remember:

Input will be "X" and output will be "Y"

What is the equation if I multiple the input by 8 and then subtract 12?

y = 8x - 12

or

y = 8 x (x) - 12
