Graph of the Linear Function y = 3x - 1

To graph the linear function y = 3x - 1, we can use the slope-intercept form of a linear equation, which is y = mx + b. In this equation, m represents the slope of the line, and b represents the y-intercept.

For the given function y = 3x - 1, the slope (m) is 3 and the y-intercept (b) is -1.

To plot the graph, we can choose a few values for x and calculate the corresponding values for y using the equation y = 3x - 1. Let's choose x = -2, 0, and 2.

When x = -2: y = 3(-2) - 1 y = -6 - 1 y = -7

When x = 0: y = 3(0) - 1 y = 0 - 1 y = -1

When x = 2: y = 3(2) - 1 y = 6 - 1 y = 5

Now, we can plot the points (-2, -7), (0, -1), and (2, 5) on a graph and draw a straight line passing through these points.

Here is the graph of the linear function y = 3x - 1:


Please note that the graph is a straight line with a positive slope of 3 and a y-intercept of -1. The line passes through the points (-2, -7), (0, -1), and (2, 5).
