Suppose the following function is graphed. y = 8/5x + 4
On the same grid, a new function is graphed. The new function is represented by the following equation.
y = -5/8x + 8
Which of the following statements about these graphs is true?

A- The graphs intersect at (0,8).
B- The graph of the original function is perpendicular to the graph of the new function.
C- The graph of the original function is parallel to the graph of the new function.
D- The graphs intersect at (0,4).
