Question

Find the equation of a line perpendicular to 2x + y = -9 that passes through the
point (8,9).

Answer 1

this is point slope theorem

step:1

set everything equal to y

step:2

find slope and make it perpendicular as this slope is -2 the perpendicular slope will be 1/2

step:3

write in a form of function

y-9 = 1/2 (x-8)
