Write the equation of a line that is parallel to y=-7 and that passes through the point (7,5)

if the line is parallel is has the same slope so it will be a horizontal line

it must pass thru the point (7,5)

y =5

y = 5

the equation y = c is a horizontal line parallel to the x-axis and passing through all points with a y-coordinate equal to c

y = - 7 is a horizontal line

the line parallel to it and passing through (7, 5 ) is therefore

y = 5 ( 5 being the value of the y-coordinate )

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.
