Give the equation of the line, perpendicular to the line with equation y=2x+1, that passes
Alina [70]

Answer:

y = - \frac{1}{2} x + 2

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 = 2x + 1 ← is in slope- intercept form

with slope m = 2

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

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{2} , thus

y = - \frac{1}{2} x + c ← is the partial equation

To find c substitute (8, - 2) into the partial equation

- 2 = - 4 + c ⇒ c = - 2 + 4 = 2

y = - \frac{1}{2} x + 2 ← equation of perpendicular line
