Write an equation, in slope-intercept form, that passes through point (-4,- 3) with slope 3.

y=3x+9

Step-by-step explanation:

Slope intercept form: y=mx + b

m= slope

b= y-intercept

-Plugin the point

-3=3(-4)+b

-3(+12) = -12 + b(+ 12)

9=b

y = 3x + 9

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.
