Write an equation of a line that passes through the point (−1,2) and is perpendicular to the line y=1/2x−3.

Respuesta :

Answer:

y = -2x

Step-by-step explanation:

slope of line y=1/2x−3     m₁ = 1/2

perpendicular line slope m₂ = -2

line y = m₂x + b        m₂: slope       b: y intercept

pass (-1 , 2)          b = y - m₂x = 2 - (-2) x (-1) = 0

perpendicular line equation: y = -2x
