Answer:
1/2 is the slope of the line
Step-by-step explanation:
To find slope, use the following equation
slope (m) = (y₂ - y₁)/(x₂ - x₁)
First, set each coordinate. Let:
(x₁ , y₁) = (8 , -6)
(x₂ , y₂) = (4 , -8)
Plug in the corresponding numbers for the corresponding variables.
m = (y₂ - y₁)/(x₂ - x₁)
m = (-8 - (-6))/(4 - 8)
Simplify. Note that two negative signs would result in a positive sign.
m = (-8 + 6)/(4 - 8)
Combine like terms.
m = -2/-4
Simplify. Divide common factors from both the numerator and denominator.
m = (-2/-4)/(-2/-2) = 1/2
1/2 is the slope of the line

Answer:
no
Step-by-step explanation:
Direct variation is of the form
y = kx
This has a constant added
y = kx+b so it is not a direct variation
If she is driving at 30 miles a hour it takes two minutes to cover a mile 60 divided by 30
if she is driving at 2 minutes a mile and is going 24 miles it will take 48 minutes
2*24 =48
solution she is a slow driver she needs to pick up the pace or she will be 3 minutes late to work
45-48=-3
