If x and y are positive integers
x y
and 4(2 ) = 2 , what is x in
terms of y ? x y
4(2 ) = 2
(a) y 2 2x y
2 (2 ) = 2
(b) y 1
y
2+x
2 = 2
(c) y
(d) y + 1
2+x = y
(e) y + 2
x = y 2

f (x) = ax + bx + c
How does a affect the graph?
Positive:
Negative:
How does c affect the graph? c is yintercept
c moves the graph up and down
