Algebra Question

Given data of height, x and stories, y is of six notable buildings in a city. height numbers: 768, 628, 518, 511, 491, 478 and stories numbers: 52, 48, 46, 43, 37, 35.  What is the scope and y intercept of this? Round the scope to three decimal places as needed. Round the y-intercept to two decimal places as needed.

For the table of data to the right, complete the following. x 39 7 9 3 (a) Express the data as a relation S. (b) Find the domain and range of S. y 9 8 8 9 9 (a) S = {O (Type ordered pairs. Type each ordered pair only once. Use a comma to separate answers as needed.) (b) The domain of S is D= (Use a comma to separate answers as needed.) The range of S is R = {). (Use a comma to separate answers as needed.)
