The equation shows the relationship between x and y:

y = −9x + 5

what is the slope of the equation?

−14
−9
−4
5

The correct option is 2. The slope of the equation is -9.

Step-by-step explanation:

The given equation is

            ..... (1)

The slope intercept form of a line is

             .... (2)

Where, m is the slope and b is y-intercept.

On comparing (1) and (2), we get

and

Therefore, the slope of the equation is -9 and y-intercept is (0,5). Option 2 is correct.

it 2

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.
