Answer:
53
Step-by-step explanation:
x - the age of the person who entered the room.
(12 + 19 + 24 + 21 + 21 + x)/6 = 25
12 + 19 + 24 + 21 + 21 + x = 150
97 + x = 150
x = 53
Answer:
y = 5x -15
Step-by-step explanation:
slope/y-int from = y =mx+b
slope = y2-y1/x2-x2
slope = 0--15 / 3-0
slope = 15 / 3
slope = 5
y-int = -15
y = 5x-15
