1. Explain how you can use the algebraic representation to determine the new coordinates of a point.

Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.

Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.

Step-by-step explanation:

In a two-dimensional plane, coordinates of a point define its exact location. The coordinate plane has two axes that are perpendicular to each other which are known as the x and y axis.

To find out the coordinates of a point in the coordinate system, follow the following procedure.

Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.

Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.

The x-coordinate and the y-coordinate determine the new coordinates of a point.

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
