Which statement is true about the graphs of the two lines y= -8x - 5/4 and y= 1/8 x + 4/5?

Step-by-step explanation:

If we have two lines of equations:

        (1)

       (2)

Where n is the slope of the line (1) and m is the slope of the line (2)

Then by definition it is fulfilled that if means that the lines (1) and (2) are perpendicular

In this case the lines are:

    (1)

       (2)

Observe that:      and    

Then it is fulfilled that  because:

Therefore the lines are perpendicular
