Find the equation of a line which passes through the point (3, –4) and has a slope of –3. Put your final answer in standard form

3x+y=5

Step-by-step explanation:

Equation of a line that has slope(m) and passes through point (a,b) is given by :-

Given: Point = (3,-4)

Slope =-3

Then, the equation of the required line:

Hence, required equation: 3x+y=5

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.
