Which statement accurately describes how to reflect point a (3, ? 1) over the y-axis? construct a line from a parallel to the x-axis, determine the distance from a to the x-axis along this parallel line, find a new point on the other side of the x-axis that is equidistant from the x-axis. construct a line from a perpendicular to the y-axis, determine the distance from a to the y-axis along this perpendicular line, find a new point on the other side of the y-axis that is equidistant from the y-axis. construct a line from a perpendicular to the x-axis, determine the distance from a to the x-axis along this perpendicular line, find a new point on the other side of the x-axis that is equidistant from the x-axis. construct a line from a parallel to the y-axis, determine the distance from a to the y-axis along this parallel line, find a new point on the other side of the y-axis that is equidistant from the y-axis as a is.

Construct a line from A perpendicular to the y-axis, determine the distance from A to the y-axis along this perpendicular line, find a new point on the other side of the y-axis that is equidistant from the y-axis

Step-by-step explanation:

we know that

The rule of the reflection of a point over the y-axis is equal to

A(x,y) >A'(-x,y)

so

The y-coordinate of both points is the same and the distance from A to the y-axis is equal to the distance from A' to the y-axis (is equidistant)

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.
