An increase in miles driven, increases the total charge, by the rate
multiplied by the distance in miles.
The correct responses;
- The equation that represents the situation is; y = 2.2·x + 2.5
- The y-intercept represents the flat fee
Method by which the above equation is arrived at:
The amount the Yellow Cab Company charges for pick up = $2.50
Amount the cab company charges per mile = $2.20
The equation that represents the situation is;
- Total charge, y = 2.2·x + 2.5
Where;
x = The number of miles driven
Details on the y-intercept's meaning;
The above equation is in the form of the equation of a straight line in slope and intercept form, y = m·x + c
Where;
m = The slope
c = The y-intercept
The y-intercept is the y-value when x = 0
- At x = 0, the y-intercept is; y = 2.2 × 0 + 2.5 = 2.5
Therefore;
- The y-intercept represent the flat fee for picking someone up.
