Answer:

No

Explanation:

These are written in slope-intercept form:

y=mx+b

m is the slope and b is the y-intercept

When two lines are perpendicular, their slopes will be opposite reciprocals of each other. For example:

$y=-2x+5\\\\y=(1)/(2)x-9$

The lines above are perpendicular because the slopes:

$m=-2\\\\m=(1)/(2)$

are opposite reciprocals.

In the given lines, the slopes are not opposite reciprocals:

$m=4\\\\m=-4$

So they are NOT perpendicular lines.
