Answer:
y =  x +
 x + 
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 = - 10x + 1 ← is in slope- intercept form
with slope m = - 10
Given a line with slope m then the slope of a line perpendicular to it is
 = -
 = -  = -
 = -  =
 =  , thus
, thus
y =  x + c ← is the partial equation
 x + c ← is the partial equation
To find c substitute (5, 7) into the partial equation
7 =  + c ⇒ c = 7 -
 + c ⇒ c = 7 -  =
 = 
y =  x +
 x +  ← equation of line
 ← equation of line
