Answer:
-5 + (-2) i think
Step-by-step explanation:
Answer:
Solution given:
9x-2y=7
making it in a form of y=mx+c
9x-7=2y
y=9/2x -7/2
Comparing above equation with y=mx+c
we get
m=9/2
Since it is passes parallel to (5,-3)
slope will be same
now
Equation of line
y-y1=m(x-x1)
y+3=9/2(x-5)
y=9/2x-5/2-3
<u>y=9/2 x-11/2 is a required equation.</u>
