y=mx+b
You have m(slope)= 3/7
And you have (x, y) (9,-2)
x=9 and Y=-2
We need to find b. So we plug all this information in to the equation
y=mx+b
-2=(3/7)(9)+b
Solve that and you will get b.
Once you have b, plug it in to the equation, along with the slope.

you wouldnt use y-y=m(x-x)??
OpenStudy (anonymous):
yes u can use that
OpenStudy (anonymous):
how would i set it up?
OpenStudy (anonymous):
u have ur gradient m = 3/7

and ur point (9,-2)
so let \[x _{1}=9 \] and \[y _{1}=-2\]
and then plug ur values in the equation \[y=m(x-x _{1})+y _{1}\]
OpenStudy (anonymous):
dus that help?
OpenStudy (anonymous):
once i solve it, would that be my answer?
OpenStudy (anonymous):
yep.u have to get a linear equation
OpenStudy (anonymous):
ok thanks alot

yw
OpenStudy (anonymous):
is 2x-9y= -3/7 the correct answer?
OpenStudy (anonymous):
actually it is
y=(3/7)x-(41/7)
or
7y=3x-41
OpenStudy (anonymous):
check the equation i gave you and see if u have done the plugging and calculations accurately
