PLease Help with one math question! What is the slope of a line perpendicular to the line with equation y = 4x + 5? 4 –4 -1/4 –5

OpenStudy (amistre64):

well, what is the slope of the stated line?

OpenStudy (amistre64):

also, what property do perpendicular slopes have?

OpenStudy (anonymous):

Wouldnt the slope be 5?

OpenStudy (amistre64):

no, 5 is the y intercept. lets go with 4 being the slope of the stated line

OpenStudy (amistre64):

now, the perp slope fulfills the property that the slopes multiply to get -1 4m = -1, what is m?
