Question

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

A. y = 2x + 6

B. y = −1/2x + 3

C. y = −1/2x + 6

D. y = 2x + 3

Answer 1

La pendiente de la recta perpendicular es -1/2, porque (2)(-1/2)=-1

\[−\frac{1}{2}=\frac{y−3}{x−6}
\\y=6−\frac{x}{2}\]


La respuesta es la C.
