Answer:
y =  x + 8
 x + 8
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 = - 3x + 13 is in this form
with m = - 3
Given a line with slope m then the slope of a line perpendicular to it is
 = -
 = -  = -
 = -  =
 = 
y =  x + c ← is the partial equation
 x + c ← is the partial equation
To find c substitute (6, 10) into the partial equation
10 = 2 + c ⇒ c = 10 - 2 = 8
y =  x + 8 ← equation of line
 x + 8 ← equation of line
