Final answer:
In the equation y = 3x + 2, y represents the dependent variable and x represents the independent variable. The equation represents a linear relationship, and by plugging in different values of x, we can find corresponding values of y. The graph of the equation is a straight line.
Step-by-step explanation:
In this equation, y = 3x + 2, the variable y represents the dependent variable and x represents the independent variable. The equation represents a linear relationship between x and y, where the coefficient of x is 3 and the constant term is 2.
For example, if we plug in x = 0, we can calculate the corresponding value of y by substituting x into the equation: y = 3(0) + 2 = 2. This gives us the point (0, 2) on the graph of the equation.
We can also find other points on the graph by substituting different values of x into the equation. By plotting these points on a graph and connecting them with a line, we can visualize the relationship between x and y.
