Answer 1

The answer is below

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
