Answer:
It's linear
Step-by-step explanation:
Linear equations have no exponents higher than a 1, which is the case for this equation cause if there's no exponent it's cause it's just a 1. Non-linear has a exponent higher than a 1, ex. 
To find slope between two given points:
(y2-y1)/(x2-x1)
Find the difference between the first two points
12-9.5/2-1 = 2.5/1 = 2.5
14.5-12/3-2 = 2.5/1 = 2.5
17-14.5/4-3 = 2.5/1 = 2.5
The rate of change between each point is 2.5
Given:
420 tropical fishes
angel fish = x
parrot fish = 6x
x + y = 420
y = 6x Choice D.
x + y = 420
y = 6x
x + 6x = 420
7x = 420
x = 420 / 7
x = 60 number of angelfish
y = 6x
y = 6(60)
y = 360 number of parrot fish
Answer:
(1,-2)
(0,-3)
(-3,0)
Step-by-step explanation:
each point on the line -x+y=-3
