Question

As you can see, the biker and his friend are having a hard time getting up the hill. They would like to get to the top safely. Two ordered pairs on the hill are given as (6, 3) and (8, 7).

Part 1: Find the slope of the hill.

Answer 1

Part 2: Now find the equation using the point slope formula.

Point Slope Formula: y – y1 = m (x – x1)


Part 3: Give an example of an equation for a line parallel to your answer from Part 2.
Part 4: Give an example of an equation for a line perpendicular to your answer from Part 2.

Answer 2

give me a couple minutes, please. too many people are asking for my help >.<

Answer 3

ok, have you found the slope yet?

Answer 4

no.. :(

Answer 5

you know how to, right?

Answer 6

it is 2

Answer 7

mhmm

Answer 8

so now to part 2

Answer 9

so, which coordinate do you wanna work with? the first or second?

Answer 10

first

Answer 11

ok. so the point-slope formula will be: y - 3 = 2(x - 6)

Answer 12

do you understand that?

Answer 13

yes. so what do i do now

Answer 14

ummm

Answer 15

we need to come up with 2 points that would have the same slope as 2

Answer 16

so...how about (6,5) and (8,9)? would they work?

Answer 17

sure

Answer 18

ok so their equation would be: y - 5 = 2(x - 6)

Answer 19

i'm not sure how to do the last part though :/

Answer 20

wait were on part 2 ?

Answer 21

lol i just did parts 1-3

Answer 22

so the 2nd part is cause im confused

Answer 23

: y - 5 = 2(x - 6) part 2 ?

Answer 24

part 1: 2
part 2: y - 3 = 2(x - 6)
part 3: y - 5 = 2(x - 6)
