points (3,6) and (4,b)
Slope is %28b-6%29.

points (a,0) and (-5,b)
Slope is b%2F%28-5-a%29

The first described line of your description has slope of %28-5-2%29%2F%283-a%29, or -7%2F%283-a%29.

Description gives equations, system%28-7%2F%283-a%29=b-6%2Cand%2C%28-7%2F%283-a%29%29%28b%2F%28-5-a%29%29=-1%29.
Simplify and solve the system.
