What is the equation of a line that passes through the point (1, 8) and is perpendicular to the line whose equation is y = x/2 + 3 ? enter your answer in the box.

y = - 2x + 10

the equation y = x + 3 is in slope- intercept form

with slope m =

given a line with slope m then the slope of a line perpendicular to it is m₂ = -

perpendicular slope = - 2

partial equation is y = - 2x + c

to find c substitute (1, 8 ) into the partial equation

8 = - 2 + c ⇒ c = 8 + 2 = 10

y = - 2x + 10 ( equation in slope-intercept form )

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
