y= 8/3x - 5
slope= 8/3
y-intercept= -5

4x + 9 = 2x - 6
x= -15/2
( negative 15 over 2 )

6^2 + 8^2 = c^2
x=10

x^3 * x^2 * y^1 * x^1 * y^2
x^6 y^3

What is a perfect square?
A number for which the square root is rational.
200
y=-3x -3
slope= -3
y-intercept= -3

20 - x = 19 + 2x
x = 1/3
(one over three)

12^2 + y^2 = 13^2
y=5

What does exterior mean?
All the space on the plane of that angle that is not the interior.
300
y= - x + 4
slope= -1
y-intercept= 4

c - 12 = 3c + 12
c = -12
