Determine the equation of each line. Write the answer in standard form using only integers as the coefficients

Question

The line through (0,9) that is parallel to the line

3x+5y=15
I need some guidance, anyone willing to help?

Answer 1

3x+5y=15
5y=-3x+15
y=-(3/5)x+3

for (0,9)
(y-9)=-(3/5)(x-0)
y= -(3/5)x+9

Answer 2

If the equations of two lines have the same coefficients for x and y they are parallel. For parallel lines, only the constant will be different. So plug in the point (0,9) and write the equation of the parallel line.

3(x - 0) + 5(y - 9) = 0
3x + 5y - 45 = 0
3x + 5y = 45

Answer 3

um use the point slope form:
y1-y2 = m(x1-x2)
