Answer:
Slope of the line perpendicular to the given line = 
Step-by-step explanation:
If two are lines are perpendicular to each other,
the product of their slopes = - 1 .
That is ,

Slope of the given line :

Hence slope of the line perpendicular to it :

Hi there! The answer is C.
We can see a reflection across the x-axis. The x-axis in this figure is an axis of symmetry. When we would measure the distance from a certain point in both of the triangles (the same point in the two triangles), this distance would be the same. Therefore this figure is reflected across the x-axis.
