A counterexample is an example which opposes an idea. The idea that all freshman girls are going to the dance can be opposed by saying that one of them will not be going. If one out of a group does not go to the dance, then the statement that all of these girl types are going would be a false statement. Most of the freshman girls will be going, aside from one. Roberta is causing problems for this statement. You'd better tell her to straighten her act up!

Answer:
Step-by-step explanation:
First find the slope:
Use the point-slope form of linear equation: 
(where m is the slope and (x₁, y₁) is a point on the line)
with the found slope and one of the points:
It would probably be x= 20 ×7
Answer:
A = 125, B = 55, C = 125
Step-by-step explanation:
A line that is cut into two by a line has two angles that equal 180. So angle A + angle D is 180. Angle D = 55 so 180 - 55 = 125. You do the same for every angle but look at the line as being cut into two in different directions for angles a and b and angles c and d.
