Consider two lines. line a is given by the function y=-4x -9, while line b contains the points (0,5) and (2, 12).
find the rate of change for both lines, then state which line has the greater rate of change.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

the answer is 5/14.

hope this .

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
