Your teacher is randomly picking two students to present a project to the class. If there are 28 students in your class, what is an expression for the probability that you and your best friend will be selected together? a. 1/ 28 b. 26!*2/ 28! c. 28!/ 26!*2 d. 1/ 28!

Hey there!

If lines a parallel, they will have the same slope. If they had different slopes, they would eventually intersect and therefore not be parallel.

On our line P, we can see the points (-6,-3) and (3,3)

We calculate the slope by dividing the difference in the y's by the difference of the x's.

Our slope is 2/3, so any line parallel would also have a slope of C. 2/3.

I hope this helps!
