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)=(-3,6)" and "(x_2,y_2)=(-2,-3)#
#m=(-3-6)/(-2-(-3))=(-9)/5=-9/5#
#"the perpendicular slope is the "color(blue)"negative reciprocal"" of m"#
#m_(color(red)"perpendicular")=-1/(-9/5)=5/9#
