What is the equation of a line that contains (-2,5) and is perpendicular to y=(1/2)x + 6?

y = - 2x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x + 6 ← is in slope- intercept form

with slope m =

Given a line with slope m then the slope of a line perpendicular to it is

= - = - = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute (- 2, 5) into the partial equation

5 = 4 + c ⇒ c = 5 - 4 = 1

y = - 2x + 1 ← equation of line
