Answer:
read below
Step-by-step explanation:
so a proportional relationship does not have y-intercepts (ex.: starting price...)
<em>"a small pizza costs $9 and each additional topping costs $.75"</em> is not proportional because it does not start at 0.
<em>"a student earns $12 for each hour she tutors"</em> for example, is proportional because it does start at 0 and does not have anything added to it.
<u>proportional: y = mx</u>
<u>not proportional: y = mx + b</u>
Step-by-step explanation:
y=mx + b
m= slope
b= y-intercept
Equation: y=-4x-14
Slope: -4
y-intercept: -14
Slope: -12/+3
Simplify: m=-4
Y-Intercept: Line passes through (0, -14)
Evidence: Used the Slope Formula (y=mx+b) to find the slope and graphed the points to find the y-interception.
Answer:
-15
Step-by-step explanation:
-15 is smaller because it is a negative number. -5 is closer to 0. -15 is farther away from 0.
