Answer:
1. 3/-1=-3; y=-3x-5; (-2, 1) 2. y=2x+5; y=x+2; (-1, 3) 3. see below
Step-by-step explanation:
1. 2/4=1/2
y intercept is 2
y=1/2x+2
3/-1=-3
y intercept is -5
y=-3x-5
p.o.i is (-2, 1)
2. 2/1=2
y intercept is 5
y=2x+5
1/1=1
y intercept is 2
y=x+2
p.o.i is (-1, 3)
3a. y is total items and x is weeks
3b. y = 4x+13, y=8x+5
3c. see below; intercept is (2, 21)
