Math 10 Week 12

This week, we learned how to write coordinates just from looking at a graph and its points.

For finding what coordinates go with the red dot, we have to first look at the x (horizontal) axis. From the fact that the dot is on the upper right corner, we know that the coordinates are going to be positive.  The x coordinate is 3. This is because the red dot lines up with 3 on the horizontal line. To find the Y coordinates, you need to look at the vertical line. The y coordinate is also 3 because the red dot lines up with 3 on the vertical lines. When writing down the coordinates, you always put x before y (x,y.) The coordinate for the red dot on this graph is (3,3.)
