Objective Essential Understanding OBJECTIVE Students will be able
Objective & Essential Understanding • OBJECTIVE: Students will be able to graph linear equations by drawing up coordinate tables. • ESSENTIAL UNDERSTANDING: Choose X. Solve for Y. Then you have a coordinate pair. Graph it!
Silently think about the answer & jot down your ideas What is a linear equation? A linear equation creates a line. Two examples: Y = X and Y = X + 2
Silently think about the answer & jot down your ideas How do we graph a linear equation? Create a Coordinate Table Y=X+2 X X+ 2 Y -2 -2 + 0 0 -1 -2 + 1 1 0 0+2 2 1 1+2 3 2 2+2 4
Number One: Y = X + 2 Y=X+2 X 1 2 3 4 X+2= Y Coordinate Pair
Number Two: Y = X + 1 Y=X+1 X 1 2 3 4 X+1= Y Coordinate Pair
Number Three: Y = X Y=X X 1 2 3 4 X = Y Coordinate Pair
Number Four: Y = X + 3 Y=X+3 X -2 -1 0 1 2 X+3= Y Coordinate Pair
Number Five: Y = X - 1 Y=X-1 X -2 -1 0 1 2 X -1 = Y Coordinate Pair
Number Six: Y = X - 3 Y=X-3 X -2 -1 0 1 2 X-3= Y Coordinate Pair
Number Seven: Y = 2 X X -2 -1 0 1 2 2 X = Y Coordinate Pair
Number Eight: Y = 3 X X -2 -1 0 1 2 3 X = Y Coordinate Pair
Number Nine: Y = 2 X + 1 X -2 -1 0 1 2 2 X + 1 = Y Coordinate Pair
Number Ten: Y = 2 X + 3 X -2 -1 0 1 2 2 X + 3= Y Coordinate Pair
Number Eleven: Y = 2 X - 1 X -2 -1 0 1 2 2 X -1 = Y Coordinate Pair
Number Twelve: Y = 2 X - 2 X -2 -1 0 1 2 2 X -2 = Y Coordinate Pair
