13. ABSTRACT REASONING Let a and b be positive real numbers. Describe how to plot (a, b), (-a, b),(a, -b), and (-a, -b).

a)

Given that and , the point is located between the +x and +y semiaxes.

b)

Given that and , the point is located between the -x and +y semiaxes.

c)

Given that and , the point is located between the +x and -y semiaxes.

d)

Given that and , the point is located between the -x and -y semiaxes.

Step-by-step explanation:

All points are represented in rectangular form, that is, numbers of the form and in which the following conditions are known:

1) If , then the point is located in the -x semiaxis, otherwise it is located in the +x semiaxis.

2) If , then the point is located in the -y semiaxis, otherwise it is located in the +y semiaxis.

Then, we proceed to analyze each case below:

a)

Given that and , the point is located between the +x and +y semiaxes.

b)

Given that and , the point is located between the -x and +y semiaxes.

c)

Given that and , the point is located between the +x and -y semiaxes.

d)

Given that and , the point is located between the -x and -y semiaxes.

the answer is a
