Question

Are the lines represented by the equations 3y+5x=9 and y+ 5/3x=3

1.parallel
2.the same line
3perpendicular
4neither

Answer 1

2 (they are the same line)

Explanation:

First get both of the lines in the same order

3y + 5x = 9

3y = -5x + 9

y = -5/3x + 3

y + 5/3x = 3

y = -5/3x + 3

Both lines are the same (y = -5/3x + 3), so the answer is 2.
