NO
c) Use the graph to estimate the
value of y when x = 2.5
+

The answer is below

Step-by-step explanation:

a) To complete the table of values for y = 3x - 1, we substitute the value of x into the equation and find y.

For x = -2, y = 3(-2) - 1 = -7; For x = -1, y = 3(-1) - 1 = -4

For x = 0, y = 3(0) - 1 = -1;    For x = 1, y = 3(1) - 1 = 2

For x = 2, y = 3(2) - 1 = 5;    For x = 3, y = 3(3) - 1 = 8

x:    -2      -1        0        1         2       3

y:    -7      -4       -1        2         5      8

b) The graph is drawn using geogebra online graphing calculator.

c) From the graph, When x = 2.5, y = 6.5

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w
