Find the slope (-2,5) and (1,-4)

Step-by-step explanation:

Slope is a surface with one end higher than the other and without no steps. It proceed at an angle.

First, you have to use the slope formula.

Slope formula:

Y₂= (-4)

Y₁=5

X₂=1

X₁=(-2)

Solve.

(-4)-5=(-9)

1-(-2)=1+2=3

(-9)/3=(-3)

Therefore, the slope is -3, which is our answer.

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.
