look at the difference between two adjacent values and that will give the slope. then determine the degree of the function

Thanks

anonymous · Answer

do not use zero as one of the values for slope.

0's y value = b in y = mx + b

anonymous · Answer

ok so like for number 7 p-128=L?

anonymous · Answer

not quite. this is the way i'd solve it:

you know your line is of the form: y = mx + b. you want to solve for m in all cases.

you are given b since when x = 0, y = m(0) + b ---> y = b

so for 7, y = L and x = p

your equation is of the form: L = mp + 128

plug in any (p, L) pair to find m:

so if you plug (p, L) = (2, 68)

68 = 2m + 128

solve for m. we get m = -30

so it is L = -30p + 128

plugging in any (p, L) pair should yield the same answer

there are other ways to do it but i think this is the method you need to use
