Which set of ordered pairs gives the polygon shown?
makvit [3.9K]
The correct answer is B.

Explanation
Since each interval mark is 1/4 of a unit, we will write this as 0.25.  For the first point, 4 interval marks to the left of the y-axis makes it a negative number; 4(0.25) = 1; this makes the x-coordinate of this point -1.  2 interval marks above the x-axis makes it positive; 2(0.25) = 0.5; this makes the y-coordinate 0.5.  This makes the first ordered pair (-1, 0.5).

The second point is on the y-axis.  This makes the x-coordinate 0.  It is 5 intervals above the x-axis; this makes it positive.  5(0.25) = 1.25 will be the y-coordinate, making the point (0, 1.25).

The third point is 3 intervals to the right of the y-axis; this makes it positive, and 3(0.25)=0.75 for the x-coordinate.  It is 3 intervals below the x-axis; this makes it negative, and 3(0.25) = 0.75, making the y-coordinate -0.75.  This puts the third point at (0.75, -0.75).
