The data follow the pattern or shape of a line. draw in a line that seems to fit most of the data. what about the data makes it linear?

△cde maps to △stu with the transformations (x, y) arrowright (x − 2, y − 2) arrowright (3x, 3y) arrowright (x, −y). if cd = a + 1, de = 2a − 1, st = 2b + 3 and tu = b + 6, find the values of a and b. the value of a is and the value of b is .

Select the sequences that are geometric.

Another type of subtraction equation is 16-b=7. explain how you would sole this equation then solve it.
