Which of the following is an arithmetic sequence? 0-2,4, -6, 8,...
O 2, 4, 8, 16,...
O-8, -6, -4,-2

This is because we are adding the same thing to each term to get the next term. In this case, we're adding 2 each time

-8+2 = -6

-6+2 = -4

-4+2 = -2

and so on. This common 2 we're adding on is known as the common difference.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
