Answer:
The answer to your question is y - 0 = 40(x - 15)
Step-by-step explanation:
                                   y = 40x + 600
Convert to                 y - y₁ = m(x - x₁)           
Process 
1.- Factor 40 in the right side of the equation
                                  y = 40(x - 15)
2.- Give the form of the point slope form
                                  y - 0 = 40(x - 15)
where 
y₁ = 0
m = 40
x₁ = 15

Answer:
n = 4
Step-by-step explanation:
Use the explicit formula of a arthmetic sequence: an = a1 + d(n - 1)
a1 = -70
d = -10
an = -100
Do all of the steps and plug all the numbers with the formula. 
So -100 = -70 - 10(n - 1)
-100 = -70 - 10n + 10
-100 = -60 - 10n
-100 + 60 = -40
-40 = -10n
-40/-10n = -10n/10
n = 4
So the final answer is n = 4. Just follow all of the steps and you will understand how I got my answer. Hope it helped!

Answer:
   Pia drove faster
Step-by-step explanation:
Speed is the ratio of distance to time. If the time is the same, the greater distance is associated with the greater speed.
Pia drove farther in 3 hours, so drove faster.
