jimthompson5910 (jim_thompson5910):
Hint: use y = mx+b
jimthompson5910 (jim_thompson5910):
m = slope
jimthompson5910 (jim_thompson5910):
b = y-intercept
OpenStudy (anonymous):
@jim_thompson5910 what's that again?

jimthompson5910 (jim_thompson5910):
example:
say the slope is 2 and the y-intercept was 3
so
y = mx+b
y = 2x + 3
would be your equation
OpenStudy (anonymous):
so would it be y= 2/3 + * ?? @jim_thompson5910
jimthompson5910 (jim_thompson5910):
no that was just my example

jimthompson5910 (jim_thompson5910):
use the slope and y-intercept given in the problem

* + 8
jimthompson5910 (jim_thompson5910):
ok you got that part correct, just not the slope
OpenStudy (anonymous):
Oh okay so what's the slope? @jim_thompson5910
jimthompson5910 (jim_thompson5910):
it's given in the problem, have another look
jimthompson5910 (jim_thompson5910):
no, it says
"slope: _____"
what goes in the blank?

oh 1/2 ? @jim_thompson5910
jimthompson5910 (jim_thompson5910):
yep
jimthompson5910 (jim_thompson5910):
so your equation is _____
OpenStudy (anonymous):
y= 8 + 2/3 ?? @jim_thompson5910

more like
y = 1/2x + 8
jimthompson5910 (jim_thompson5910):
y = mx + b
y = 1/2x + 8 ... replace m with 1/2, b with 8
jimthompson5910 (jim_thompson5910):
m is your slope
b is your y-intercept
