y = 2x - 1

Answer 1

The equation y = 2x - 1 represents a linear relationship between x and y. The coefficient of x is 2, which means that for every increase of 1 in x, y increases by 2. The constant term -1 represents the y-intercept, which is the point where the line intersects the y-axis. In this case, the line intersects the y-axis at the point (0,-1).
