Someone please help me.

Identify an equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1)

Which of the following pairs of functions are inverses of each other? o a. f(x)=x72+8 and 96-9 = 7/x+2) =8 o b. f(x)= 6(x - 2)+3 and g(x) - *#2-3 o c. $4) = 5(2)-3 and 90- 4*: 73 o d. f(x) = 6)-12 and 910 – +12

Do,h = (7, 9) (14, 18) the scale factor is
