a)Use the data shown above and express in words the amount the cab company charges per ride and per mile.
cost = mx + b
b)Write an equation in slope-intercept, point-slope, or standard form. Explain why you chose the form you did.
cost = m (1) + b
cost = 1.10(1) + 1.20
^ the slope I got was 0?
c)What does the y-intercept mean in the context of this problem? Hint: What do you pay when you step into the cab?
1.20
no, the slope you got was 1.10 I suspect. Of course I do not see your data.
a) The cab company charges $1.20 as a fixed fee (per ride) and an additional $1.10 per mile (per mile).
b) The equation that represents the cost can be written in slope-intercept form as: cost = $1.10x + $1.20. I chose this form because it allows for clear identification of the slope ($1.10) and the y-intercept ($1.20) in the equation.
c) In the context of this problem, the y-intercept of $1.20 represents the fixed fee the cab company charges when you step into the cab, regardless of the distance traveled. This amount is independent of the distance and will be charged even if you don't travel any miles.
a) To express the amount the cab company charges per ride and per mile, we can use the equation `cost = mx + b`, where `m` represents the cost per mile and `b` represents the fixed cost per ride.
b) The equation you wrote `cost = m(1) + b = 1.10(1) + 1.20` seems incorrect. It should be `cost = mx + b = 1.10x + 1.20`, where `x` represents the number of miles traveled. The slope `m` you found, 0, appears to be incorrect. Please check your calculations again.
c) The y-intercept in this problem refers to the value of `b` in the equation `cost = mx + b`. In this case, the y-intercept represents the fixed cost you have to pay when you step into the cab, regardless of the distance you travel. Therefore, the y-intercept value of 1.20 means that you pay $1.20 as the base fare when you enter the cab, before accounting for any distance traveled.
