Explanation:
#"calculate the slope m using the "color(blue)"gradient formula"#
#•color(white)(x)m=(y_2-y_1)/(x_2-x_1)#
#"let "(x_1,y_1)=(29,36)" and "(x_2,y_2)=(57,57)#
#m=(57-36)/(57-29)=21/28=3/4#
#"the slope of a line perpendicular to m is"#
#•color(white)(x)m_(color(red)"perpendicular")=-1/m#
#m_("perpendicular")=-1/(3/4)=-4/3#
