Answer:
at twice the father's rate of speed. At this rate; how many miles would the bicycle rider travel in 9 hours?
Step-by-step explanation:
at twice the father's rate of speed. At this rate; how many miles would the bicycle rider travel in 9 hours?
Parallel lines have the same slope, but different y intercepts.
Perpendicular lines have slopes that multiply to -1 (assuming neither line is vertical). So if m is the perpendicular slope of -1/5, then (-1/5)*m = -1 solves to m = 5. Another way to look at it is to flip the fraction and the sign of -1/5 to get to 5/1 or just 5.
