how high is that point off the x axis (think of it as the ground)
anonymous

4...
jim_thompson5910
  • jim_thompson5910
no, 2 actually
anonymous

wouldnt 2 be closer though

anonymous
  • anonymous
oh
jim_thompson5910
  • jim_thompson5910
so you see how that point is (1,2) ?
anonymous
  • anonymous
ohh wait i see in the screenshot
anonymous
  • anonymous
yes
jim_thompson5910
  • jim_thompson5910
what is the other point?
anonymous
  • anonymous
2,0?
jim_thompson5910
  • jim_thompson5910
(2,0) yes
jim_thompson5910
  • jim_thompson5910
(1,2) and (2,0) are the two points
jim_thompson5910
  • jim_thompson5910
use the slope formula \[\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\] to find the slope
anonymous
  • anonymous
so -2
jim_thompson5910
  • jim_thompson5910
yes the slope of the line through those two points is -2
anonymous
  • anonymous
so that's the answer?
jim_thompson5910
  • jim_thompson5910
oh wait, it's x = 1 to x = 3 NOT x = 1 to x = 2
jim_thompson5910
  • jim_thompson5910
there's one other point on the graph that has an x coordinate of 3 what is the y coordinate here?
anonymous
  • anonymous
-6
jim_thompson5910
  • jim_thompson5910
so the two points you'll use are (1,2) and (3,-6)
jim_thompson5910
  • jim_thompson5910
use the same slope formula
anonymous
  • anonymous
so-4
jim_thompson5910
  • jim_thompson5910
good
anonymous
  • anonymous
yay thanks so much can you please help with 1 more?
jim_thompson5910
  • jim_thompson5910

Which logarithmic graph can be used to approximate the value of y in the equation 5y = 12? (5 points) http://gyazo.com/09247132268a7180076b6fd9c7b33364
jim_thompson5910
  • jim_thompson5910
It says \[\Large 5^y = 12\] right?
anonymous
  • anonymous
yes sorry
jim_thompson5910
  • jim_thompson5910
when you isolate y, what do you get
anonymous
  • anonymous
how would i do that? like do i square root 5 i dont know lol
jim_thompson5910
  • jim_thompson5910
what undoes exponents?
anonymous
  • anonymous
square roots?
jim_thompson5910
  • jim_thompson5910
logs do
anonymous
  • anonymous
oh sorry
jim_thompson5910
  • jim_thompson5910
if we solve for y, we get \[\Large 5^y = 12\] \[\Large y = \log_{5}(12)\] \[\Large y = \frac{\log(12)}{\log(5)}\] \[\Large y \approx 1.543959\]
jim_thompson5910
  • jim_thompson5910
So find the function where if you plug in x = 12, you'll get roughly y = 1.543959
anonymous
  • anonymous
okay
anonymous
  • anonymous
wait so if i graphed them would the answer show up as one of theoptions?
jim_thompson5910
  • jim_thompson5910
look at your options which choice has (12, 1.543959) on it?
jim_thompson5910
  • jim_thompson5910
obviously B and C are out because the y coordinates of the point with x coordinate 12 is negative
anonymous
  • anonymous
d?
jim_thompson5910
  • jim_thompson5910
why D?
anonymous
  • anonymous
because it's 12,1.5
jim_thompson5910
  • jim_thompson5910
what is the coordinates of that blue point for choice A?
anonymous
  • anonymous
12,1
jim_thompson5910
  • jim_thompson5910
good
jim_thompson5910
  • jim_thompson5910
so that rules out A
anonymous
  • anonymous
yay thanks!!
