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

14-6 \2-(-2)
anonymous
  • anonymous
alright, so thats 8/4 which is 2, that was the formula for the slope
anonymous
  • anonymous
ok
anonymous
  • anonymous
m = 2 now, cause were using M as a symbol of slope... pick an equation, -2, 6 or 2, 14?
anonymous
  • anonymous
-2,6
anonymous
  • anonymous
y - y1 = m(x - x1) plug everything in
anonymous
  • anonymous
y-6=2(x-(2))
anonymous
  • anonymous
what would y and x be to plug in
anonymous
  • anonymous
y and x aint plug ins, theyre just y and x
anonymous
  • anonymous
ok
anonymous
  • anonymous
id give u the answer, but "Im not allowed to" xD, but distribute the 2 to the ()'s
anonymous
  • anonymous
a?
anonymous
  • anonymous
oh wait no
anonymous
  • anonymous
no, its B
anonymous
  • anonymous
and u get 10 from the distribute right?
anonymous
  • anonymous
can i ask one more? :|

holy hell, my computer lagged, but yeah

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)
anonymous
  • anonymous
alright, we can skip the first part which was y2 - y1 / x2 - x1 cause they already gave u the slope...
anonymous
  • anonymous
yea
anonymous
  • anonymous
\[y - (-2) = 4(x - 3)\]
anonymous
  • anonymous
distribute the 4 to (x-3)
anonymous
  • anonymous
oh wait, i already gave u the answer xD
anonymous
  • anonymous
its A

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

lol sorry, and np

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.

  • anonymous
and that would be D right?
anonymous
  • anonymous
this is the last i promise haha
anonymous
  • anonymous
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
anonymous
  • anonymous
im thinking it would be B
anonymous
  • anonymous
ok
anonymous
  • anonymous
because its the start off amount, the -150x is how much she loses a day
anonymous
  • anonymous
yea so thats why I'm lost cuz in a way its decreasing and increasing
anonymous
  • anonymous
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!
anonymous
  • anonymous
ight thx again
anonymous
  • anonymous
thx bro i got a 100%
