After creating a scatter plot, you notice that all the points on the plot lie along a horizontal line. this means that:
a. the data set has a positive trend.
b. the data set has a negative trend.
c. all the x-values in the data are the same.
d. all the y-values in the data are the same.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
