Question

You are 18 miles away from home. You start biking home at a speed of 6 miles per hour. Write an equation in slope-intercept form that represents the distance away from home "y" after "x" hours. Y= How many hours will it take to get home? Hours

Answer 1

y = 18 - 6x

Explanation:

Given :

Speed or rate = 6mph

y = distance away from home

x = hours biked

Initial distance from home = 18 miles

General form of Slope - intercept form of an equation :

y = mx + c

Where ;

m = gradient or slope = rate of change

c = intercept or initial value or amount, always constant

x = independent variable

y = dependent variable

Hence,

For the question above :

Distance away from home, depends on the number of hours biked

y = 18 - 6x
