Thanks to anyone who helps!

Rate of change, aka the slope, change in y over change in x.  We can pick any two points, let's go with (0,29), (1,23).

m = (23 - 29)/(1 - 0) = -6

Rate of change -6

Initial value, which is the y intercept here, 29.

Initial Value 29.

We have the slope and y intercept so the equation is

y = -6 x + 29

Let's check (4,5),   y =-6(4)+29 = -24 + 29 = 5, good

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

d) 48
