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)=(-17,23)" and "(x_2,y_2)=(21,25)
m=(25-23)/(21-(-17))=2/38=1/19
"the slope of any perpendicular line is"
•color(white)(x)m_(color(red)"perpendicular")=-1/m=-1/(1/19)=-19

Explanation:
The slope
We know that the product of slope of two perpendicular lines is
