x = 1
200
Simplify: 3(2x+5) +5
6x + 20
200
Is this a function? Why or why not?
No, it is not a function because one input has two outputs.
200
What is the slope-intercept formula?
y = mx + b
200
What is the solution to the system of equations?
x = -3y + 10
y = -14
The solution is (52, -14)
300

x = 9
300
Graph the following inequality:
X > 5
open circle at 5 and arrow going to the right.
300
Is this a function? Why or why not? 
Yes, it is a function because it passes the vertical line test.
300
What is the slope of this line? Is it a positive or negative slope?
It's a negative slope.
m = -2/5
