1000m equals 1km so 600m equals 0.6km.
Parallel lines are in the same plane, never intersect, and have the same slope.
Point slope equation for point (h,k) and slope m is given by
y-k=m(x-h)
compare given equation with formula
we get h=-7, k=3
so the required point is (-7,3)
60 minutes in an hour
60 x 8 = 480
his class is 480 minutes long
