Slopes may positive, negative, zero, or undefined. What does a negative slope tell you about the graph of the linear equation?
The line is decreasing if the slope is negative; it is increasing for a positive slope.

All sides are congruent in a regular polygon.

What is Euler's Formula? Tell what each variable represents.
Euler's Formula is F + V - E = 2. F = faces V = vertices E = edges

What is the output value (y) for the linear equation y = 1/2x + 2 if the input values (x) is -2?
y = 1/2 * (-2) + 2 = -1 + 2 = 1 y = 1

Find the volume of a square pyramid if the base has dimensions of length = 2cm and width = 2cm and it's height is 6cm. V = 1/3(l x w x h)
V = 1/3 (2 x 2 x 6) = 8 cubic cm

Draw an example of angles that are complementary and angles that are supplementary. True or False? Adjacent angles must be either complementary or supplementary?
Drawings may vary. Complementary angles must be 2 or more angles equal to 90º and supplementary angles must be 2 or more angles equal to 180º. Adjacent angles do not have to be complementary or supplementary. They only have to be next (adjacent) to each other.

Is there an outlier in the data below? What effect does it have on the measures of central tendency? Stem| 0 1 2 3 4 5 Leaves| 8,8,9, 6,7 2,3,8 0,1 9
The outlier is 59. If the measures of central tendency are calculated WITHOUT the outlier we can see the effect. Without the outlier (59), our calculations are: Range: (31 - 8) =23 Mode: 8 (no effect) Median: 19.5 (drops 2.5) Mean: 19.2 (drops 3.6...)

If the equation of a line is y = -2x + 4, what ordered pairs would NOT be on graphed on this line? Tell which is the y-intercept and which is the x-intercept. Answer choices: (0, -4) (0, 4) (2, 0) (-2, 0)
y-intercept is (0, -4) x-intercept is (-2, 0)

A cylinder with radius of 2cm and a height of 5cm is placed on top (base-side down) of a rectangular prism with the following dimensions: length = 4cm, width = 4cm and height = 5cm. Find the surface area of the composite (two 3D shapes on top of each other) shape. SA of cylinder: 2πr(r+h) SA of rectangular prism: 2(l x w) + 2(l x h) + 2(w x h)
SA of cylinder + SA of prism - 2(SA of circular base) 87.92 + 96 - 2(12.56) = 158.8cm squared

Two lines intersect. One angle is 48º. Draw a picture of this diagram. Find the measures of all other angles. Name which angle relationships you used to determine the measure of each angle.
Check drawing. There should be two angle measures of 48º and two angle measures of 132º. The angle relationships are vertical angles and supplementary angles.

Graph a line plot that organizes the following data values: 6, 6, 6, 7, 2, 4, 4, 2, 6, 5, 5, 4, 3, 3, 5, 3 Find the range, mean median, and mode for the following data set. Tell which measure of central tendency is best for the data set.
Line plot should be a number line from 2 to 7 with an x for each data point above its value. Range: 7 - 2 = 5 Mean: 4.44 Median: 4.5 Mode: 6 The mode is too high and the range is easily affected by an outlier. Therefor, the mean and median, very similar values, are the best measures of central tendency for this data.
