Answer:
y = 2x - 11
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 = - [tex]\frac{1}{2}[/tex] x + 1 ← is in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (8, 5) into the partial equation
5 = 16 + c ⇒ c = 5 - 16 = - 11
y = 2x - 11 ← equation of perpendicular line
