What are equations?
Equations are relations between two or more variables, used to find the value of an unknown variable from the known value of other variables.
How do we solve the given question?
We are given the equation y = 3x - 1. We are asked to complete the table, for the given values of x: -2, -1, 0, 1, 2, 3.
To find the y variable, for the given x's, we substitute each value of x, one at a time in the equation.
- Value of y when x = -2 is, y = 3(-2) -1 = - 6 - 1 = -7.
- Value of y when x = -1 is, y = 3(-1) -1 = - 3 - 1 = -4.
- Value of y when x = 0 is, y = 3(0) -1 = 0 - 1 = -1.
- Value of y when x = 1 is, y = 3(1) -1 = 3 - 1 = 2.
- Value of y when x = 2 is, y = 3(2) -1 = 6 - 1 = 5.
- Value of y when x = 3 is, y = 3(3) -1 = 9 - 1 = 8.
We put all these values of y, for the corresponding value of x in the table. The completed table is attached.
