Final answer:
The question is about the relationship between distance traveled and the price of airfare. The equations provided show different relationships between distance and price, with varying slopes and y-intercepts.
Step-by-step explanation:
The given question is about the relationship between the distance traveled and the price of airfare. The question provides four equations in the form of Y = mx + b, where Y represents the price of airfare and x represents the distance traveled. The coefficients m and b represent the slope and y-intercept of the line, respectively.
The equations Y = 0.30, Y = 0.70, Y = 0.30x + 200, and Y = 0.70x + 200 show different relationships between distance and price. The coefficient 0.30 represents that for every unit increase in distance traveled, the price will increase by 0.30 units. Similarly, the coefficient 0.70 represents that for every unit increase in distance traveled, the price will increase by 0.70 units. The equations with intercepts specify a base price of $200.
