Answer:

Average rate of change is the slope of two coordinate points or values.

Therefore,

Given values are :

(1960,668) and (1970,760)

Slope = (760 - 668)/(1970 - 1960)

Slope = 92/10

Rate of change will be 9.2 gallons/passenger

Answer:

y = -5x - 21

Step-by-step explanation:

Given in the question,

equation of a parallel line

y = -5x + 6

point through which it passes

(-4,-1)

Step1

Find the gradient of the equation given, as it is parallel so it will have same gradient

equation of straight line

y = mx + c

where m is gradient

c is y intercept

y = -5x + 6

m =-5

Step2

Find y-intercept

-1 = -5(-4) + c

-1 = 20 + c

c = -20 - 1

c = -21

Step3

form the equation

y = -5x - 21
