It's a Hit

Copy onto cards the equations shown below, one per card. Shuffle the cards and place them face down in a pile. Write the equations on a sheet of paper.

Each partner selects a card and graphs the equation shown. (Remember, to graph an equation, make a table to find solutions.) Then partners take turns trying to guess which equation the other partner graphed by calling out ordered pairs. If the ordered pair names a point on the line you graphed, say "Hit." If the ordered pair does not name a point on the line you graphed, say "Miss." Try to be the first to guess which of the ten equations your partner graphed. (Hint: You should be able to guess the equation after you have guessed any two points on the line.)

Equations to put on cards:
y = -3x + 3		y = 6 - x	y = -x + 10	y = 2x + 1
y = 5x - 1	y = -2x + 9	y = 4x	y = x - 6	y = 2x
