Which of the following lines are parallel to this line y = 4x + 2

y=4x+7

Step-by-step explanation:

The line parallel to y=4x+2, through a given point is (-1,3)

x=-1, y=3

y=mx+b

3=4(-1)+b

3=-4+b (NEGATIVE 4 AND POSTIVE 4 CANCELS OUT)

+4 +4

('3+4=7)

B=7

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
