Determine the equation of each line. Write the answers in standard form using only integers as the coefficients.
The line through (0,9) that is parallel to the line 3x+5y=15
First find the slope of the line 3x+5y= 15. i.e bring it to the std form
y=mx+c, 5y = -3x+15 or y = (-3/5)x+15.hence m=(-3/5)
Let the required eq'n be m(x-x1) = (y-y1).The line passes thro'h (0,9)
and slope m = (-3/5).substitute these values in the req'ed eq'n

we get -(3/5)(x-0)=(y-9)
-3(x-0) = 5(y-9) [multiply by 5 on both sides]
-3x-0 = 5y-45
5y+3x = 45 is the req'd eq'n
