How can coordinate proof be used to prove two lines are parallel?

1 answer:

8 0

You can use the coordinates to find the slope of each line. If you can show the two slopes are equal, then the lines are parallel.

Side note: If the lines are vertical, and never cross, then they will be parallel despite having an undefined slope. This is one of the exceptions to the rule.

Answer:

0.50

Step-by-step explanation:

P(A|B)=P(A and B)/P(B) is the formula to find a conditional probability when A and B are not independent.
