Question

the perpendicular from the orgin to a line meets it at (-2,9). Find the equation of the line?​

Answer 1

Step-by-step explanation:

slope of the perpendicular line is -9/2.....(m1)

for perpendicular lines m1×m2=-1

slope of the line is 2/9 .....(m2)

by using y=mx+c

m is 2/9

to find c substitute y=9 and x=-2

c=85/9

9y=2x+85
