Which of the following lines is perpendicular to y=4x+2

4y + x = 4c

Step-by-step explanation:

given equation of line

               y = 4 x + 2

comparing with equation

               y = m₁ x + c

m₁ = 4           c = 2

we know,

condition for perpendicular lines is

                  m₁ ×  m₂ = -1

now,            4 × m₂  = -1

                         m₂ = -1/4.................(1)

now,    we know

               y = m₂ x + c

putting value of  equation (1)

             4y + x = 4c    

to get the value of c we need a point

hence, the answer comes out to be 4y + x = 4c

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
