Aline with a slope of 1/2 passes through the point (2,-1). what is the equation of this line ?

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
