Final answer:
To graph the function y = 3x, create a table of values and plot the points on a graph. The equation represents a straight line with a slope of 3 and a y-intercept of 0.
Step-by-step explanation:
To graph the function y = 3x, we need to create a table of values and plot the points on a graph. The equation represents a straight line with a slope of 3 and a y-intercept of 0. To create the table, we can choose different values for x and calculate the corresponding y-values by substituting them into the equation. For example, when x = 0, y = 3(0) = 0. Using this approach, we can generate a table of values and then plot the points on a graph, connecting them to create the line.
