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.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

i believe that the slope of the line is -5
