When we have exponents multiplied with the same base we add them so 5^5*5^10=5^15
If it is g(x) composed of f(x): 1 If it is g(x) times f(x): -27
(g•f)(-3) is multiplication, (gof)(-3) is composition.
So slope intercept form is y=mx+b
m=slope b=y intercept
convert current equation to slpe intercept
y-4=x-8
add 4 to both sides
y=x-4
tada
ANSWER
3) b
EXPLANATION
Given that:

and

Recall that the sine and cosine functions are equal for complementary angles.
This implies that,


Y= -1/3x+5
the y-intercept is 5 and the slope is -1/3
