Coordinate Points Linear Relationships
Points are written as two coordinates. The form
is P1 (2 , 3) which means Point 1 is located at
X2 and Y3 on a graph.

Example 1 Is the coordinate point (2 , 19)
a solution to the equation Y 17 X ? The
given values are X2 and Y19. Putting the values
for X and Y into the equation we have 19 17
2 or 19 19 Yes it is a solution.

• Example 2 The ordered pair (2, 20) is the
  solution to which of the following equations?
• Y 40/ X Or Y 40 X
• 40 / 2 Or 20 40(2)
• 20 20 20 80
• Y X / 40 is Correct.
