Question

Use the image to answer the question.
graph of line y=7x+13. Include and label the points: (0, 13), (1, 20), (2,27). Gridlines should only appear at whole numbers. Here all horizontal gridlines are okay but vertical gridlines should only appear at -4, -3, -2, -1, 0, 1, 2, 3, 4

Write the function of the graphed arithmetic sequence.

(1 point)

TIP: Use the slope-intercept form to help you write the function.

Answer 1

Since the graph is y = 7x + 13 and the points given are (0,13), (1,20), (2,27), the arithmetic sequence is
a_n = 7n + 13
(using n = 0 gives a_0 = 13, n = 1 gives a_1 = 20, etc.).
