@jim_thompson5910 Can you please help?
jimthompson5910 (jim_thompson5910):
is there a typo on 3x + 2y = 10 ?
OpenStudy (anonymous):
yea!, 3x + 2y < 10
jimthompson5910 (jim_thompson5910):
is there a line under any of the inequalities?
OpenStudy (anonymous):
nope

the first task is to graph y > 2x - 1
jimthompson5910 (jim_thompson5910):
you do this by
step 1) graphing the line y = 2x - 1
step 2) make this a dashed line
step 3) shade above the dashed line
jimthompson5910 (jim_thompson5910):
make sense?
OpenStudy (anonymous):
Yea, whats next
jimthompson5910 (jim_thompson5910):
graph the second inequality

I dont know how
OpenStudy (anonymous):
hello?
jimthompson5910 (jim_thompson5910):
graphing 3x + 2y < 10
step 1) graph 3x + 2y = 10
step 2) make this a dashed line
step 3) shade below the dashed line
jimthompson5910 (jim_thompson5910):
let me know if that helps or not
OpenStudy (anonymous):
I dont know how to graph the second equation though

can you show me?
jimthompson5910 (jim_thompson5910):
how about we solve for y
jimthompson5910 (jim_thompson5910):
3x + 2y = 10
2y = -3x + 10
y = -3x/2 + 10/2
y = -3/2x + 5
jimthompson5910 (jim_thompson5910):
does that help?
OpenStudy (anonymous):
yes, very much so, :) thanks
