Paper For Above instruction

The provided graph from a ride-sharing service illustrates how the total cost of a ride correlates with the distance traveled, specifically in miles. To analyze this relationship, we interpret the graph using the linear model, which requires identifying key components such as the base fee, the cost per mile, and deriving the equation that describes the total fare as a function of miles.

Part 1: Calculating the Base Fee

The base fee in a ride-sharing context refers to the flat starting charge applied regardless of distance traveled. To determine this, we examine where the line crosses the y-axis (the total cost when miles traveled is zero). According to the graph, the y-intercept occurs at approximately $3.00. Therefore, the base fee charged by the ride-sharing service is $3.00.

Part 2: Calculating the Rate of Increase (Cost per Mile)

The rate of increase in cost per mile can be found by selecting two points on the line to calculate the slope. Suppose we choose the points (x₁, y₁) = (5 miles, $8.00) and (x₂, y₂) = (10 miles, $13.00). The slope (m) is then calculated as:

m = (y₂ - y₁) / (x₂ - x₁) = ($13.00 - $8.00) / (10 - 5) = $5.00 / 5 miles = $1.00 per mile

This indicates that the cost increases by $1.00 for each additional mile traveled.

Part 3: Identification of Slope and y-Intercept

From the previous calculations, the slope (m) of the line is $1.00 per mile. The y-intercept (b), which corresponds to the base fee when zero miles are traveled, is approximately $3.00.

Part 4: Derivation of the Slope-Intercept Equation

The linear equation modeling the ride cost (C) as a function of miles (x) is derived using the slope-intercept form:

C(x) = mx + b

Substituting the identified values:

C(x) = 1.00x + 3.00

This equation predicts the total fare based on the number of miles traveled.

Part 5: Extrapolating the Cost for a 50-Mile Ride

Using the equation C(x) = 1.00x + 3.00, the cost for a 50-mile ride is:

C(50) = 1.00 * 50 + 3.00 = $50 + $3 = $53.00

Thus, the estimated fare for a 50-mile ride is $53.00.

Conclusion

In summary, the ride-sharing service charges a base fee of $3.00 with an additional $1.00 per mile traveled. The linear model accurately represents the relationship between distance and fare, enabling prediction of costs for trips beyond the observed data.
