Let a =107° and b=42°;
So cos 107° cos 42° + sin 107° sin 42° = cosa.cos42 + sina.sinb = cos(a-b)
and cos 107° cos 42° + sin 107° sin 42° = cos(107-42) = cos(65°)

Answer:
Slope is -3
y-intercept is -3 and equation is y=-3x-3
First we have to find a common denominator
8×3=21
7/8×3=21/24
2/3×8=16/24
21-16=5
answer is 5/24
