point slope form:  y = mx + b
m = slope, b = y-intercept
y = -13x + b  through (5,7)
 
Use the given point as (x,y) to find b
 
7 = -13(5) + b
7 = -65 + b
b = 72
 
y = -13x + 72

y – 7 = –13(x – 5)

tMy apologies.  Must have been half asleep when I answerd this one.
The point slope form is: y - y1 = m(x - x1)
 
(x1, y1) = (5,7) ,  m = -13
 
y-7 = -13(x-5)
