It takes Miranda 30 minutes to paint 6 chairs. If Miranda paints at a constant rate, what is the constant of proportionality that relates y, the number of chairs painted in x minutes?

5

Step-by-step explanation:

Divide 30 by 6, since this will find the number of chairs she can paint in 1 minute:

30/6

= 5

So, the constant of proportionality is 5, since she can paint 5 chairs in a minute.

  1/5

Step-by-step explanation:

You want k so that ...

  y = kx

You are told that y=6 when x=30, so ...

  6 = k·30

  6/30 = k = 1/5

The constant of proportionality is 1/5.

  y = (1/5)x

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
