Write a direct variation equation that relates the variables. Then graph the equation.
Alex can ride his bike at a rate of 7 miles per hour. His total distance in T hours is D
rate = distance / time ( I remember this because speed = miles / hours )
7 = D / T where D is in miles. Lets solve for D by multiplying both sides by T .
D = 7T
