Question

explain how to plot a point in the rectangular coordinate system. give an example with your explanation. to plot the point (a,b) in the rectangular coordinate system, if a is positive, go |a| units from zero along the and if a is negative, go |a| units from zero along the then, if b is positive, go |b| units parallel to the and if b is negative, go |b| units parallel to the as an example, the point is plotted on the graph to the right. (type an ordered pair.)

Explanation:

In a rectangular - coordinate system, for an ordered pair (a, b), the first number a represents the horizontal displacement and the second number b represents the vertical displacement. If a is positive, move |a| units to the right along the x - axis; if a is negative, move |a| units to the left along the x - axis. Then, if b is positive, move |b| units up parallel to the y - axis; if b is negative, move |b| units down parallel to the y - axis. For example, to plot the point (3, 2), start at the origin (0, 0), move 3 units to the right along the x - axis and then 2 units up parallel to the y - axis.

Answer:

To plot the point (a,b) in the rectangular coordinate system, if a is positive, go |a| units right from zero along the x - axis and if a is negative, go |a| units left from zero along the x - axis. Then, if b is positive, go |b| units up parallel to the y - axis and if b is negative, go |b| units down parallel to the y - axis. As an example, the point (3, 2) is plotted.
