Ithink the slope of f is -10 and g is -1 but i can't figure out how to perform equations with the information i was given

A) 140
↪(3f+2g)(1)
=3f(1)+2g(1)
=3×50+2×(-5)
=150-10
=140

b) 10
↪(fog)(-1)
=f[g(-1)]
=f(-3)
=10
❇NOTE:
▶(f+g)(x)=f(x)+g(x)
▶(fog)(x)=f[g(x)]
{Just observe the corresponding value of x in respective functions to evaluate f(x=something) and g(x=something)

What’s the improper fraction?

Is it multiple choice
