Question 918979: Please find the slope of a line perpendicular to the line 5x-7y=39. Thanks for your help.
Answer by ewatrrr(24785) (Show Source): You can put this solution on YOUR website!
the standard slope-intercept form for an equation of a line is
where m is the slope and b the y-intercept.
5x-7y=39 Solving for y
y = x - 39/7, m = (5/7)
the slope of a line perpendicular: m = -7/5 (negative reciprocal)
