16. slope ab= slope ac= slope bc=

17. which slope in item 16 is the steepest?

18. is triangle abc a right triangle? if so show why.

19. write the equation of a line through c that is parallel to ab (or just give coordinates)

20. write the equation of a line through b that is perpendicular to ac.

The answer to your question is:

Step-by-step explanation:

Data

A (-2, 0)

B (2, 3)

C (5, -1)

Process

Slope AB    m = (3 - 0) / (2 + 2)

                  m = 3/4

Slope AC    m = (-1 - 0) / 5 + 2)

                      = -1 /7

Slope BC    m = (-1 -3)/ (5 - 2)

                      = -4/3

17. Which slope in item 16 is the steepest? __AC___

18. Is triangle ABC a right triangle? If so show why.  Yes, it's a right triangle because slope AB is perpendicular to slope AC, then they form an angle of 90°.    (3/4)(-4/3) = -1

19. Write the equation of a line through C that is parallel to AB (or just give coordinates)

slope = 3/4

point (5,-1)

                              (y - y1)= m(x - x1)

                               y + 1 = 3/4(x - 5)

                              y + 1 = 3/4x - 15/4

                              y = 3/4x - 15/4 -1

                              y = 3/4 x - 19/4

20. Write the equation of a line through B that is perpendicular to AC.

B (2, 3)

slope = 7

                           y - 3 = 7(x - 2)

                          y - 3 = 7x - 14

                          y = 7x - 14 + 3

                          y = 7x - 11

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
