a) 6x + y = 9
b) 6x - y = -9
c) x + 6y = 9
d) x - 6y = -9
OpenStudy (shamim):
the equation of line will b\[y-y _{1}=m(x-x _{1})\]
OpenStudy (shamim):
u hv slope of ur given line is\[m=-6\]
OpenStudy (shamim):
so any line which is parallel to ur given line hv slope\[m=-6\]
OpenStudy (anonymous):
so its y-(-3)=-6(x-2)

OpenStudy (shamim):
so the equation of ur required line will b\[y-(-3)=-6(x-2)\]
OpenStudy (shamim):
ya
OpenStudy (anonymous):
i got b. 6x-y=-9
OpenStudy (anonymous):
am i correct?
OpenStudy (anonymous):
formula =>
\[(y-y1)=m(x-x1)\]
use this formula
where m=-6 and (x1 , y1)=(2,-3)
u will get the equation

ans is option a ....
OpenStudy (anonymous):
wait is the answer a or b?
OpenStudy (anonymous):
a
OpenStudy (anonymous):
6x+y=9

s.... solve by substituting ...
OpenStudy (anonymous):
noo ....y+6x=9
OpenStudy (anonymous):
\[y-(-3)=-6(x-2) \]
\[y+3-6x+12\]
\[y+6x=12-3\]
\[y+6x=9\]
OpenStudy (anonymous):
in options its 6x+y=9 same as y+6x=9
