Step-by-step explanation:

Coordinates of Points

A point is the basic relationship displayed on a graph. Each point is defined by a pair of numbers containing two coordinates.

A coordinate is one of a set of numbers used to identify the location of a point on a graph.

Identifying the x-coordinate

The x-coordinate of a point is the value that tells you how far from the origin the point is on the horizontal, or x-axis. To find the x-coordinate of a point on a graph:

- Draw a straight line from the point directly to the x-axis.

- The number where the line hits the x-axis is the value of the x-coordinate.

Identifying the y-coordinate

Now that you know how to find the x-coordinate of a point, you have to be able to find the y-coordinate.

The y-coordinate of a point is the value that tells you how far from the origin the point is on the vertical, or y-axis. To find the y-coordinate of a point on a graph:

- Draw a straight line from the point directly to the y-axis.

- The number where the line hits the axis is the value of the y-coordinate.

Notation for Identifying Points

Once you have the coordinates of a point you can use the ordered pair notation for labeling points. The notation is simple. Points are identified by stating their coordinates in the form of (x, y). Note that the x-coordinate always comes first.

the solution is 12x-6y

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
