-6x + y < 3
6x + y < 3
6x - y < -3
The correct inequality is not listed
@AriPotta
OpenStudy (aripotta):
ok, so come up with the equation and move it to standard form
OpenStudy (aripotta):
like, make the equation in slope-intercept form. so find the y-intercept and slope. then rearrange that into standard form
OpenStudy (anonymous):
\[y=mx+b y _{2}-y _{1}=m(x _{2}-x _{1})\]
OpenStudy (anonymous):
they are separated at by^2

I am lawst
OpenStudy (anonymous):
lost?
OpenStudy (aripotta):
look at the graph and tell me what the y-intercept is
OpenStudy (anonymous):
find x when y=o, then find y when x=0
OpenStudy (dmezzullo):
y=1

i think it's 3
OpenStudy (anonymous):
1 is x intercept
OpenStudy (dmezzullo):
Ohh
OpenStudy (anonymous):
so, you got (0,3) and (1,0)
OpenStudy (dmezzullo):
Yes sir

substitute it into the formula y=mx+b
OpenStudy (anonymous):
m is the slope of the line
OpenStudy (dmezzullo):
It has to be D bc the inequality equation ain't listed
OpenStudy (dmezzullo):
Is it
OpenStudy (anonymous):
yes

probably
OpenStudy (anonymous):
is the answer 3x+y=>3
OpenStudy (aripotta):
the slope is 6 tho
OpenStudy (anonymous):
why? can you show me please?
