WARM UP  Using the following table and y = mx + b;  1) What is the y?  2) What is the b? xy

USING : y = mx + b  What does this describe?  It is constant (it is going to be a number and stay that number) Answer: m or b

USING : y = mx + b  What does this describe?  Stays “x” when writing an equation.  Answer x

USING : y = mx + b  What does this describe?  Dependent Variable  Answer: y

USING : y = mx + b  What does this describe?  Is in the second column of a table.  Answer: y
