2 because it is the number being added to the zero intercept in the equation
Answer:
She bought 6 erasers.
Step-by-step explanation:
Week 1=50
week 2= 50×2=100
week 3=100×2=200
week 4=200×2=400
week 5=400×2=800
week 6=800×2=1600
week 7=1600×2=3200
week 8=3200×2=6400
so the answer is 6400
Answer:
y = .75x - 4.5
Step-by-step explanation:
y = mx + b
m = slope ; b = y-int
slope = rise/ run = 3/4 = .75
y = .75x + b
Because it is hard to determine the exact y-intercept, we plug in a point (2,-3):
-3 = .75(2) + b
-3 = 1.5 + b
-4.5 = b -->
y = .75x - 4.5
Linear, because it would be a function something like y = .46 + .2x. Which is linear.
