The first number in an ordered pair tells you which variable?
The X Variable.... remember, (X,Y)
100
What does the "m" in y=mx+b tell you?
Slope?
100
When looking at it from left to right, will the following line be going UP or DOWN?
y= -2x + 16
DOWN, because the slope is negative.
100
What is the solution to the following system of equations?
y= 3/4x - 4
y= -1/2x - 4
(0,-4)
100
A point on the graph, represented by (X,Y)
Ordered Pair

When plotting an Ordered Pair, where should you start?
The Origin
200
What does the "b" in y=mx+b tell you?
Y-Intercept
200
What is the Y-Intercept of the equation:
y=6x
The Origin, (0,0), because there is no +b
200
What is the solution to the following system of equations?
y= 3x - 1
y= 3x + 3
NO SOLUTION! **SAME SLOPE, but different Y-intercept, means that the lines are parallel and will NEVER TOUCH!**
200
What type of equation is y=mx+b?
Linear Equation
300
If I were graphing the ordered pair, (-4,7), what direction should I move first?
Left
300
What is the Y-Intercept in
y=5x - 7
-7
300
The Equation Y=-8 will make what type of line?
Horizontal

When Jimbo began lifting weights in middle school, he could only bench press 50lbs. After that, his bench press went up 20lbs per year.
Write a Linear Equation to describe how much weight Jimbo can bench press each year.
W= 20Y + 50
300
The spot where two lines in a System of Equations intersect.
The Solution
400
If I were graphing the ordered pair, (5,-9), what two direction do I need to move from the origin?
Right 5, then Down 9
400
What is the slope in
y=9x+3
9
400
The Equation X=5 will make what type of line?
Vertical Line
400
What is the solution to the following system of equations?
y= 3x
y= 3
(1,3)
400
The solution to the system of equations:
y=4x-12
y=4x+8
No Solution
500
If I were graphing the ordered pair, (6,0), how far Up do I have to move?
Do not move Up. The Y-value is 0, which means you do not go Up or Down.
500
What is the slope in
y= 5 - 2x
-2
500
What is the Rise/Run of the Slope for the equation:
y = -x
-1/+1 or -1 over +1
500
What is the solution to the following system of equations?
y= -4/5x + 2
y= -4/5x + 2
INFINITE SOLUTIONS! **Equations are EXACTLY the SAME, so they are the same line**
500
The solution to the System of Equations:
y=8x+4
y=8x+4
