1 Evaluate if m = 6 & n = 4 m2 ÷ n -1 62 ÷ 4 -1 12 ÷ 4 -1 3 – 1 2
Susan evaluated the following expression and got 2. Is her answer correct? Justify your answer. Evaluate if m = 6 & n = 4 m2 ÷ n -1 62 ÷ 4 -1 12 ÷ 4 -1 3 – 1 2

2 Susan evaluated the following expression and got 2
Susan evaluated the following expression and got 2. Is her answer correct? No, 62 = 36, Evaluate if m = 6 & n = 4 m2 ÷ n -1 62 ÷ 4 -1 36 ÷ 4 -1 9 – 1 8

3 Which statement is TRUE about the equation y=2x+1?
y is the independent variable. x is the independent variable. Both x & y are independent variables. Both x & y are dependent variables.

4 Which statement is TRUE about the equation y=2x+1?
b) x is the independent variable. Remember: X can stand alone (independent) because it has 2 legs. Y needs help (dependent) because it has only 1 leg.
