How do you change -y to a positive?
Flip the sign to make y positive.
Ex: y > 3x
2(-21 + 6)
-30
Solve for y
3x + 5y = 15
y=-3/5x + 5
What makes a function?
When x does not repeat.
How do you turn a negative exponent into a positive?
Ex: y-3
Turn it into a fraction (by moving the base to the denominator, adding a one in the numerator, and changing the exponent sign.)
Ex: 1/y3
