Question 663704
-9+5y=6 as a linear equation
5y=15
y = 3, which is a straight horizontal line at y=3 passing though all x points.
There is no slope.
...
A parallel line would need to be also horizontal but passing (-1,-4), where the horizontal line passes along y=-4 at every x point, including -1.
Again, there is no slope; otherwise, they would eventually intersect.
