evaluate y=3+2x,the dependent variable when the independent variable has the value 2
To evaluate the expression y = 3 + 2x when the independent variable x has the value 2, you need to substitute the value of x into the expression and calculate the corresponding value of y.
1. Write out the expression: y = 3 + 2x.
2. Substitute the value of x as 2 into the expression: y = 3 + 2 * 2.
3. Perform the multiplication first: y = 3 + 4.
4. Add the numbers together: y = 7.
Therefore, when the independent variable x has the value 2, the value of the dependent variable y is 7.
