Are the segments through the origin and the points listed perpendicular? explain.
a. ,10), ,9)
b. ,6), , −6)

a. Not perpendicular.

b. Perpendicular.

Step-by-step explanation:

We need to check whether the segments through the origin and the points listed perpendicular.

Product of slopes of two perpendicular lines is -1.

(a) The given points are (9,10) and (10,9).

Slope of line segment through (0,0) and (9,10) is

Slope of line segment through (0,0) and (10,9) is

Product of slopes is

Therefore, the line segments through the origin and the points (9,10) and (10,9) are not perpendicular.

(b) The given points are (9,6) and (4,-6).

Slope of line segment through (0,0) and (9,6) is

Slope of line segment through (0,0) and (4,-6) is

Product of slopes is

Therefore, the line segments through the origin and the points  (9,6) and (4,-6) are perpendicular.

on your paper it doesn't say the answer but the the answer is altitude

step-by-step explanation:

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.
