Answer: False

Explanation:

In order for lines to be perpendicular, their slopes must be opposite reciprocals.


y=-(5)/(2)x+4\qquad \rightarrow \quad m=-(5)/(2)\\\\\\y=(5)/(2)x-3\qquad \rightarrow \quad m=(5)/(2)

Their slopes are opposites (opposite signs).
\checkmark

Their slopes are NOT reciprocals (fractions flipped)
