Answer:
The slope is 3/8
The y intercept is 75/8
Step-by-step explanation:
The slope is found by
m= (y2-y1)/(x2-x1)
= (9-6)/(-1- -9)
= (9-6)/(-1+9)
=3/8
The y intercept is found by
y = mx+b where m is the slope and b is the y intercept
y = 3/8 x+b
9 = 3/8(-1) +b
Getting a common denominator
72/8 = -3/8 +b
Add 3/8 to each side
75/8 = b
3/8, 9 3/8
y= mx+b
m=(y2-y1)/(x2-x1)
L (-9, 6) and M(-1, 9)
slope is:
y- intercept is:
you can use either or for the last one
Since it is growing at 5% per year, at the end of each year the population will be 1.05 times what is was at the start of the year.
Start with 110,000 and multiply by 1.05 a total of 16 times to get the population at the end of 16 years.
P = 110,000 x 1.0316 ≅ 176,518
