Based on the trend line, what is the best prediction for the number of candies in the jar when 30 students visit her?

Multiplying an even number of negative numbers gives an answer that is choose from:

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Are the corresponding angles congruent? explain why or why not.
