| Question 679197:  i am having a lot of trouble figuring out how to do this problem, the directions say to plot three ordered pair solutions of the given equation and then draw a line through the three points, y = -3x + 1,  the answer in the back of the book is (3,3) im just not understanding 1. how they get 3,3? 2. if they ask to plot 3 points where are the other 2?  and the directions in the chapter suggest that i make up 3 numbers for x and use the equation to solve for y... im so lost... i dont understand this at all.. and all of the problems are similar to this one.

      (Show Source): 
You can put this solution on YOUR website! Given y = -3x + 1, start with the intercepts.
 ...
 y intercept, b, is 1
 Plot (0, 1)
 ...
 x intercept is where y equal 0
 0 = -3x + 1
 -1 = -3x
 x =
  Plot (
  , 0) ...
 
  ...
 Not sure where (3,3) originated either, as it is not a point on the line.
 If x is 3, then
 y = -3(3) + 1 = -9 + 1 = -8
 Plot(3,-8)
 ...
 If y is 3, then
 3 = -3x + 1
 3 - 1 = -3x
 2 = -3x
 x =
  Plot(
  ,3) .....................
