Question 43517
Distance = Rate * Time
a) Write a linear function that expresses the distance traveled, d, as a function of time, t.
After zero hours, you traveled 0 miles, so: (0,0)
After one hour, you traveled 60 miles, so: (1,60)
M = (y2 - y1)/(x2 - x1) = (60 - 0)/(1 - 0) = 60/1 or just 60
{{{y - y1 = m(x - x1)}}}
{{{y - 0 = 60(x - 0)}}}
{{{y = 60x}}} where {{{y}}} is distance and {{{x}}} is time
{{{y/60 = x}}}
