Answer:
Slope=2.
Step-by-step explanation:
Slope=y1-y2/x1-x2
Where
X1,y1,=(-5, -11) X2,y2=(6,11).
Slope=-11-11/-5-6
=-22/-11
=22/11
=2
Slope is 2
Let
A = population of town A,
B = population of town B,
C = population of town C.
Because the population of town B is 50% greater than that of town A,
B = 1.5A (1)
Because the population of town C is 20% greater than that of town A,
C = 1.2A (2)
From (1), obtain
A = B/1.5 = (2/3)B (3)
Substitute (3) into (2).
C = 1.2*(2/3)*B = 0.8B
Divide each side by 0.8.
1.25C = B
This result means that B is 25% greater than C.
