Answer:
y = 5x + 26
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}{5}[/tex] x + 1 ← is in slope- intercept form
with slope m = - [tex]\frac{1}{5}[/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}{5} }[/tex] = 5 , thus
y = 5x + c ← is the partial equation
To find c substitute (- 5, 1) into the partial equation
1 = - 25 + c ⇒ c = 1 + 25 = 26
y = 5x + 26 ← equation of perpendicular line
