A line passes through the point (-2,3) and has a slope of 7. Write an equation in slope-intercept form

y = 7x + 17

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Step 1: Define

Slope m = 7

Random point (-2, 3)

Step 2: Substitute

y = 7x + b

Step 3: Find b

3 = 7(-2) + b

3 = -14 + b

17 = b

Step 4: Write linear equation

y = 7x + 17

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.
