Locate the coordinates of the three highlighted points on the graph of the triangle at right and write them as ordered pairs $(x,y)$ .

First quadrant plane triangle, with vertices at the following points: (2, comma 1), (4, comma 7), and (6, comma 1).

Hint:

To determine the x-coordinate of a point, find the horizontal distance from the origin.
To determine the y-coordinate of a point, find the vertical distance from the origin.

Partial Answer:

One ordered pair is $(2,1)$ .

Hint 2:

Don't forget to put the $x$ -coordinate before the $y$ -coordinate in your ordered pair. $(x,y)$
