One of the tables shows a proportional relationship.
beks73 [17]

Answer:

See attached

Step-by-step explanation:

The graph of a <u>proportional linear relationship</u> is a line that <u>passes through the origin</u> (0, 0).

From inspection of the given tables, the <u>linear equations</u> for each table of points is:

  • Table 1:  y = x + 1
  • Table 2:  y = x/2
  • Table 3:  y = x + 2
  • Table 4:  y = 2x + 1

The only equation for which y = 0 when x = 0 is y = x/2  →  Table 2.

Given points from Table 2:

  • (2, 1)
  • (4, 2)
  • (6, 3)
  • (8, 4)

To <u>graph the line</u>, plot the given points and draw a line through them (see attached).

Hence,

f'(9) = (22 * 9) + 5 = 198 + 5 = 203
