Linear Equation and Boarding Rate

Linear Equations in the real world Problem 1)  A cab company charges a $3 boarding rate in addition to its meter which is $2 for every mile. What is  the equation of the line  that represents this cab company's rate? | Problem 2)  A cab company charges a $5 boarding rate in addition to its meter which is $3 for every mile. What is  the equation of the line  that represents this cab company's rate? | Slope of this line  : 3 y-intercept of line: 5 Equation of this line(slope intercept form)  : y = 3x +5 Problem 3)  A cab company charges a $3 boarding rate in addition to its meter which is $? for every mile. What is  the equation of the line  that represents this cab company's rate? | Slope of this line  : ? y-intercept of line: 3 Equation of this line(slope intercept form)  : y = ? x +3 Problem 4)  A cab company charges a $4 boarding rate in addition to its meter which is $ ? for every mile. What is  the equation of the line  that represents this cab company's rate? | Slope of this line  : ? y-intercept of line: 4 Equation of this line(slope intercept form)  : y = ? x + 4 Problem 5)  A cab company does not charge a boarding fee but then has a meter of $4 an hour. What  equation  represents this cab company's rate? | Slope of this line  : 4 y-intercept of line: 0 Equation of this line(slope intercept form)  : y = 4x Problem 6)  A cab company does not charge a boarding fee but then has a meter of $4 an hour. What  equation  represents this cab company's rate? | Slope of this line  : 4 y-intercept of line: 0 Equation of this line(slope intercept form)  : y = 4x Problem7)  A cab company charges a $1 boarding fee and has a meter of $1/3 an hour. What  equation  represents this cab company's rate? | Slope of this line  : 1/3 y-intercept of line: 1 Equation of this line(slope intercept form)  : y = 1/3x+1 Need help with this page's topic? | At how many mnutes do both companies charge the same amount? | Never, the slope of the graphs of their rates is the same. Parallel lines  never intersect. | | At how many minutes do both companies charge the same amount? | 20 Minutes| | |
