The perimeter of a square
varies directly with the side length. The
point-slope form of the equation for this
function is y - 4 = 4(x - 1). Write the
equation in standard form
Harvey rides his bike at an
average speed of 12 miles per hour. In
other words, he rides 12 miles in 1 hour,
24 miles in 2 hours, and so on. Let h be
the number of hours he rides and d be
distance traveled. Write the equation for
the relationship between distance and
time in point-slope form.
Geoff paddles his canoe at
an average speed of 3.5 miles per hour.
After 5 hours of canoeing, Geoff has
traveled 18 miles. Write an equation in
the point-slope form to find the total
distance y for any number of hours x.
