Choose the correct scientific notation:  

Graph the system of inequalities. Then choose the graph below that matches your graph. y ≥  -2x + 4 y < 2x - 8

Decide if the following pairs of lines are parallel, perpendicular, or neither. y = 2x + 3 and y = 1/2x – 3             [c1] y = 1/3x + 2 and y = -3x + 1           [c2] y = 4x – 2  and y = 4x + 2                 [c3]

Divide (long division): (x3 – x2 – x – 15) ÷ (x – 3)

What is the slope and y-intercept of the line in the graph below?     Slope = [m1] y-intercept = [y1]  

Megan simplified the following . Find the FIRST place she made a mistake. Subtract:

Which of the following graphs represents the inequality -2x + y ≤ 3  

Find the slope and y-intercept for each of the following. (3pt each) Enter numbers only, no letters. y = 3x – 2           slope = [m1], y-intercept = [b1] 2x – y = 5           slope = [m2], y-intercept = [b2]

Which of the following is a solution to the system 3x – 2y = 4  and 2x – 3y = 1?  

What type of boundary would be used to graph each of the following inequalities? (You don’t need to graph them, just choose the type of boundary you would use if it was graphed.) 2x + y < -5        [b1] 3x - 2y ≤ 4        [b2] x + 3y > 8          [b3] x – 4y ≥ -6          [b4]
