Evaluate:
10 + 5 - 8 + 3 - 1
9
Find the slope between
(4, 3) and (6, 8)
5/2
Evaluate f(x) = 3x - 1 ; f(-2)
f(-2) = -7
Solve by substitution:
y = -3x + 7
4x - 2y = -4
(1, 4)
What is the capitol of Arizona?
Phoenix
Simplify:
5(3x - 1) + 10
5
Write the equation of the line with a slope of -4 and a y-intercept of (0, 8)
y = -4x + 8
Evaluate f(x) = (1/2)x + 4 ; f(8)
f(8) = 8
Solve by substitution:
3x - y = 2
x = 4y - 3
(1, 1)

Is the relation a function?
{(7, 4), (-4, 3), (7, -8), (0, 1)}
No (the input {7} repeats)
Solve by elimination:
6x - 5y = 5
-12x+ 4y = -4
