Answer:
Not perpendicular
Step-by-step explanation:
Convert it to y-intercept form first:
5x - 4y = -1
-4y = -5x - 1
y = 5/4x + 1/4
4x - y = -9
-y = -4x - 9
y = 4x + 9
y = 5/4x + 1/4
y = 4x + 9
From the slopes, they are not considered perpendicular because one of the line slope is not a <em>negative reciprocal</em> of the other line slope.
