Algebra 1 Semester 1 Review Part 8

51A) Identify the common difference in each arithmetic sequence

A. 21, 15, 9, 3, -3...

• d = -6

• d = 6

• d = 5/7

• d = -4.5

• d = 4.5

• d = 5/7

• f(3) = -14

• f(3) = 14

• f(3) = 26

• f(3) = -26

53) Which sequence is represented by y = 10x - 29 where x represents the term number and y represents the term?

• A. 1, -28, -57, -86

• B. -29, -19, -9, 1

• C. -19, -9, 1, 11

• D. 10, -19, -48, -77

54) Antonio is arranging tiles according to the pattern below. Which represents the explicit formula for the arithmetic sequence that models Antonio's pattern.

• 5, 2, -1, -4

• 5, 8, 11, 14

• 5, 8, 11, 14

• -30, -42, -54, -66

56A) State the y-intercept and slope of the lines below.

y = 4x - 8

• Slope = 4

  y-int = -8

• Slope = -8

  y-int = 4

56B) State the y-intercept and slope of the lines below.

y = 7x + 3

• Slope = 7

  y-int = 3

• Slope = 3

  y-int = 7
