The equation that best describes the relationship between x and y is y = 9 + 3x.
The equation that best describes the relationship between the values x and y shown in the table is y = 9 + 3x.
In this equation, the constant term (b) is 9 and the coefficient of x (m) is 3. To find the values of y, you can substitute different values for x and calculate the corresponding y values using the equation.
This equation represents a linear relationship between x and y, where y increases by 3 units for every 1 unit increase in x.
This can be seen by plotting the points on a graph, where they form a straight line.
