Question

The table represents the equation y = 2 – 4x. Use the drop-down menus to complete the statements. The x-values are the . The y-values are the . The missing value in the table for x = –1 is y = .

Answer 1

the x values are the inputs
the y values are the outputs && the missing value in the x = -1 is y = 6

Answer 2

The x-values are independent variables, y-values are dependent variables, and for the equation y = 2 - 4x, the missing y-value when x = -1 is 6.

The x-values are the independent variables, and the y-values are the dependent variables.

They represent the dependence of y on x. For the equation y = 2 – 4x

we can determine the missing value in the table for x = –1 by substituting –1 for x in the equation:

y = 2 – 4(–1) = 2 + 4 = 6

Therefore, the missing value for y when x equals –1 is 6.

This process demonstrates how we create a data table by plugging different x-values into the equation and then calculating the corresponding y-values, which can then be graphically represented on a graph to show the relationship between x and y.
