"perpendicular slope "=-3/5

Explanation:

"establish the slope of the given line"

"the equation of a line in "color(blue)"slope-intercept form" is.

•color(white)(x)y=mx+b

"where m is the slope and b the y-intercept"

"rearrange "5x-3y=8" into this form"

rArr3y=5x-8rArry=5/3x-8/3

"with slope m "=5/3

"Given a line with slope m then the slope of a line"
"perpendicular to it is"

•color(white)(x)m_(color(red)"perpendicular")=-1/m

rArrm_("perpendicular")=-1/(5/3)=-3/5
