hey mate

here is your answer

the slope of the line perpendicular line =y2-y1/x2-x1

=>9-0/-2-0

=>-9/2

the condition of the the perpendicularity

is that the slope of the lines would be -ve reciprocal.

thus

m=-1/-9/2

=2/9

where m is the slope of the line

thus ,by one point slope form

the equation is given by

=>y-y1=m(x-x1)

=>y-9=2/9(x+2)

=>9(y-9)=2(x+2)

=>9y-81=2x+4

=>9y=2x+85 is the equation.

Answer:

2x-9y+85=0

Step-by-step explanation:

slope of OC =9-0/-2-0=-9/2

OC Perpendicular AB

slope of AB=2/9

equation of line AB is

y-9=2/9(x+2)

9y-81=2x+4

2x-9y+85=0
