99 given the standard form of the linear equation below, solve for y in terms x and state the slope of the line. −15x + 5y = 20 slope =

Use the slope-intercept form: y = mx + b

Fill in the things in: -15x + 5y = 20

Add into both sides "15x": -15x + 15x + 5y = 20 + 15x

Simplify the form: 5y = 20 + 15x

Add the x form into the area where it is supposed to be: y = (20 + 15x)/5

Simplify: y = 4 + 3x

Change around the two pieces: y = 3x + 4

3 is in the "m" area, also known as the slope, is the answer.

Hope this helped!

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.

f(x) = y

f(-3) = -5
