Question

1. Calculate the slope of Graph D. Explain or show your reasoning
2. Calculate the slope of Graph E. What situation could the graph represent

3. On the blank grid , draw a line that passes through the indicated point and has the slope -2.

Answer 1

Answer:

Step-by-step explanation:

1). Slope of a line shown on the graph will be,

   Slope = $\frac{\text{Rise}}{\text{Run}}$

              = $\frac{-4}{1}$

              = -4

2). Slope of the given horizontal line can be determined by,

    Slope = $\frac{\text{Rise}}{\text{Run}}$

    Since, rise of the given line is zero.

    Therefore, slope of the given horizontal line will be 0.

3). Slope of the line passing through the indicated line = -2

    Therefore, a line which has a rise = -2 and run = 1 can be drawn on the given blank grid (As attached).

Answer 2

Answer:

Step-by-step explanation:

1. -4. Explanations vary. Sample explanation: for each horizontal change of 1, the vertical change is -4, so the slope of the line is -4.

2. 0. Responses vary. Sample response: The amount of rainfall on a day with no rain.

3. A graph through the indicated point with a slope of -2.
