The graph shows the distances traveled by two buses.

the equation y = 55x represents the distance, y, bus a travels in x hrs.

which equation could represent the distance traveled by bus b?

• y = 40x
• y = 60x
• y = 65x
• y = 70x

Because for any x value on the graph, the line for bus B lies below the line for bus A, the y-value must be smaller, which means we are multiply by a smaller coefficient. All of the options have coefficients greater than 55 except for y=40x. So, y=40x is the correct option.

Hope this helps!! :)
