Question

The equation y = 0.5x represents the distance Henry hikes in miles

per hour. The graph represents the rate that Clark hikes. Determine
which hiker is faster. Explain

Answer 1

Clark is faster because the slope of his graph is bigger.

Explanation:

The slope of Henry’s graph can be found as 0.5 because the equation is in slope intercept. (The coefficient of the x value is the slope)

Since there is a point at (12,18) in Clark’s graph, you can conclude Clark’s slope as 18/12. (Rise over run)

18/12 = 1.5

1.5 is bigger than 0.5 so Clark travels faster.
