Hello!!! Princess Sakura here ^^
Step-by-step explanation:
If you solve for y and graph it you'll find out that these equations will be perpendicular.
The first equation when solved for y will be...[tex]y=\frac{5}{4}x +\frac{3}4}[/tex]
The second equation when solved for y will be...[tex]y=-\frac{5}{4}x +\frac{3}{4}[/tex]
If you really need to graph it go ahead but if you're to lazy like me you can know by looking at the equations. If you look at the y-intercept they are the same that means they share a common point. So they can't be parallel if they are touching. Now if we look at the slope one is positive and the other is negative that means one is pointing upwards and the other one is pointing downward, that makes them perpendicular.
