Final Answer: The equation of the line is \(\boxed{y = 2x + 4}\).

Steps

Step 1 :The equation of a linear function is given by the formula \(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept.

Step 2 :The slope can be calculated by taking the difference in y-values divided by the difference in x-values between any two points.

Step 3 :Let's take two points from the table, point1 = (-1, 2) and point2 = (1, 6).

Step 4 :Calculate the slope: \(m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{6 - 2}{1 - (-1)} = 2.0\). So, the slope of the line is 2.

Step 5 :The y-intercept can be found by substituting the slope and one of the points into the equation and solving for \(b\).

Step 6 :Substitute the slope and point1 into the equation: \(2 = 2*(-1) + b\). Solving for \(b\), we get \(b = 4.0\). So, the y-intercept is 4.

Step 7 :Therefore, the equation of the line is \(y = 2x + 4\).

Step 8 :Final Answer: The equation of the line is \(\boxed{y = 2x + 4}\).
