Find the value of the function.

1.
f(x)=4x+9,f(2)f(x) = 4x + 9,\quad f(2)
2.
f(x)=−6x−5,f(−3)f(x) = -6x - 5,\quad f(-3)
3.
f(x)=x−5,f(6)f(x) = x - 5,\quad f(6)
4.
f(x)=6x−9,f(−5)f(x) = 6x - 9,\quad f(-5)
5.
f(x)=6x−8,f(−2)f(x) = 6x - 8,\quad f(-2)

Give the slope k of each line.

6.
y=x−9y = x - 9
7.
y=6+xy = 6 + x
8.
y=−3+2xy = -3 + 2x
9.
y=−2x+6y = -2x + 6
10.
