Answer 3

Graph of y = 2x - 1

To plot the graph of the equation y = 2x - 1, we can use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

In this case, the slope (m) is 2, and the y-intercept (b) is -1.

To plot the graph, we can start by plotting the y-intercept, which is the point (0, -1). From there, we can use the slope to find additional points on the line. The slope of 2 means that for every increase of 1 in the x-coordinate, the y-coordinate increases by 2.

Let's plot a few more points to get a better idea of the line's shape:

When x = 1, y = 2(1) - 1 = 1. So, we have the point (1, 1). When x = -1, y = 2(-1) - 1 = -3. So, we have the point (-1, -3).

Now, let's plot these points on a graph:


As we can see from the graph, the line y = 2x - 1 has a slope of 2 and passes through the point (0, -1). It is a straight line that increases as we move from left to right.
