Determine the slope of the line 6x + 3y + 10 = 0.

−2
negative one half
one over two
2

Option A is correct.

Step-by-step explanation:

Given Equation of Line: 6x + 3y + 10 = 0

We have to find Slope.

We find Slope by rewriting the given equation in slope intercept form that is

y = mx  + c where m is lope of line.

6x + 3y + 10 = 0

3y = -6x - 10

So, Slope of given line = -2

Therefore, Option A is correct.

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.
