7  Question:  Write the equation for this line:  Answer  Y = 4/3x – 2 2/3 OR y = 4/3x – 8/3 EQUATIONS : 1000

8  Question:  Give a valid definition of slope  Answer  The rate of change of a linear graph. OR The change in y-value divided by the change in x-value SLOPE: 200

9  Question:  What is the slope of the graph in this equation: y-2 = 2/3(x-1)  Answer  2/3 SLOPE : 400

10  Question:  Given this table, what is the slope of a line through these points.  Answer  -5/2 SLOPE : 600 XY 12 3-3

11  Question:  Given the following sequence: 1, 7, 13, 19, …; with 1 being step 0, what is the rate of change?  Answer  +6 SLOPE : 800

12  Question:  Find the slope of the line that intersects the following two points: (4, 6) (4, 0)  Answer  Slope is undefined SLOPE : 1000

13  Question:  What is the x-value of the y-intercept  Answer  x=0 Y-INTERCEPT : 200

14  Question:  What is the y-intercept of this graph: Y = 2/3x – 4/3  Answer  (0, -4/3) Y-INTERCEPT : 400
