Answer:
The friend's claim is not correct
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal yo -1)
Example
A given line has a slope of [tex]m_1=1/2[/tex] ---> (is less than 1)
the slope of the line perpendicular to the given line is equal to
[tex]m_1*m_2=-1[/tex]
substitute
[tex](1/2)*m_2=-1[/tex]
[tex]m_2=-2[/tex]
so
the perpendicular line don't have a positive slope
therefore
The friend's claim is not correct
