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

Y = -8x - 5/4slope here is -8 or -8/1
y = 1/8x + 4/5...slope here is 1/8

what u have here are negative reciprocal slopesnegative reciprocal of a number can be found by flipping the number and changing the sign. So the negative reciprocal of -8/1 is 1/8 (see how I flipped the number and changed the sign)...and when u have negative reciprocal slopes, this means that ur lines are perpendicular.

U ok yeah u go do that
