Question

Determine whether the graphs of the pair of lines are parallel5x - y = 254y - 20x = - 4

Answer 1

We will have the following:

We will solve for y in each function first:

`y=5x-25`

&

`4y=20x-5\Rightarrow y=5x-(5)/(4)`

From this we can see that their slopes are equal, thus the lines will be parallel.
