Answer:
Step-by-step explanation:
ummm so it doesnt have a y axis...
i think it should be
y=4x which is the parallel
and y= -1/4x which is perpendicular, it doesnt really pass through (4,3) so ot sure what ur teacher wants really
6x-5y=4
6x+3y=30
Move variable to the left
5y=6x-4
Reorder the terms
5y-6x=-4
Change the signs
-6x+5y=-4
3y=-6x+20
3y+6x=20
