  y = 1/2x +7

Step-by-step explanation:

I like to start with the 2-point equation for a line.

  y = (y2 -y1)/(x2 -x1)(x -x1) + y1

  y = (9 -8)/(4 -2)(x -2) +8 . . . . . fill in point values

  y = 1/2(x -2) +8 . . . . . simplify a bit

  y = 1/2x +7

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
