Question

Hi. I need help with the answer to number 8. Thanks

Answer 1

Given that Allie identifies the coordinates of point D as:

$(3,7)$

You need to remember that a point has this form:

$(x,y)$

Where "x" is the x-coordinate and "y" is the y-coordinate.

Instead of writing the point in that form, Alli wrote it as:

$(y,x)$

You can identify in the Coordinate Plane that point D is 7 units right to the Origin and 3 units above the Origin. Therefore, its x-coordinate is:

$x=7$

And its y-coordinate is:

$y=3$

Hence, the answer is: Alli wrote point D in this form:

$(y,x)$

And that is incorrect because the order of the coordinates of a point is:

$(x,y)$

The coordinates of point D are:

$(7,3)$
