Question

Write the equation of the line that passes through (–2, 6) and (2, 14) in slope-intercept form.

y = 2x – 2
y = 2x + 10
y = 0.5x + 7
y = 0.5x – 4

Answer 1

please help

Answer 2

@BweadedChicken

Answer 3

y2 - y1 / x2 - x1 <-- first formula, put everything in place then let me see

Answer 4

14-6 \2-(-2)

Answer 5

alright, so thats 8/4
which is 2, that was the formula for the slope

Answer 6

ok

Answer 7

m = 2 now, cause were using M as a symbol of slope...
pick an equation, -2, 6 or 2, 14?

Answer 8

-2,6

Answer 9

y - y1 = m(x - x1) plug everything in

Answer 10

y-6=2(x-(2))

Answer 11

what would y and x be to plug in

Answer 12

y and x aint plug ins, theyre just y and x

Answer 13

ok

Answer 14

id give u the answer, but "Im not allowed to" xD, but distribute the 2 to the ()'s

Answer 15

a?

Answer 16

oh wait no

Answer 17

no, its B

Answer 18

and u get 10 from the distribute right?

Answer 19

can i ask one more? :|

Answer 20

holy hell, my computer lagged, but yeah

Answer 21

Write the equation of the line that passes through (3, –2) and has a slope of 4 in point-slope form.

y + 2 = 4(x – 3)
y – 3 = 4(x + 2)
x – 3 = 4(y + 2)
x + 2 = 4(y – 3)

Answer 22

alright, we can skip the first part which was y2 - y1 / x2 - x1 cause they already gave u the slope...

Answer 23

yea

Answer 24

\[y - (-2) = 4(x - 3)\]

Answer 25

distribute the 4 to (x-3)

Answer 26

oh wait, i already gave u the answer xD

Answer 27

its A

Answer 28

oh lol i was about to go through lol thx :)

Answer 29

lol sorry, and np

Answer 30

Anne has a total of 3,500 golf balls at home. She loses some golf balls when she goes out on the driving range daily. The number of golf balls, h(x), can be represented by the function h(x) = –150x + 3,500, where x is the number of days she plays golf. Suppose 3,500 changed to 4,000. What does this mean in the context of the problem?

Changing 3,500 to 4,000 means the initial number of golf balls decreased.
Changing 3,500 to 4,000 means the initial number of golf balls increased.
Changing 3,500 to 4,000 means the daily number of golf balls lost decreased.
Changing 3,500 to 4,000 means the daily number of golf balls lost increased.

Answer 31

and that would be D right?

Answer 32

this is the last i promise haha

Answer 33

Im not 100% sure cause it says 3500 is how much she has at home, so in a way its increased, but also decreased cause she can lose em all

Answer 34

im thinking it would be B

Answer 35

ok

Answer 36

because its the start off amount, the -150x is how much she loses a day

Answer 37

yea so thats why I'm lost cuz in a way its decreasing and increasing

Answer 38

its alright, ask me as much questions as u want any time im online, im usually only chatting anyways, but i gotta head out, cya!

Answer 39

ight thx again

Answer 40

thx bro i got a 100%
