2questions worth 50 ! q1 bill works at a golf course and gets paid hourly. the table shows the amount he is paid for different numbers of hours worked. find the unit rate of the table to determine how much bill is paid per hour. q2 write the equation for a line thta has a rate of change of -3 and passes through the point (3, -5).

Q1

144.90/18=8.05

Therefore Bill earns $8.05 per hour.

Q2

Rate of change is slope.

So m=-3

y=mx+b

-5=-3*3+b

b=4

y=-3x+4

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
