The given equation is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
In this case, the slope is 2 and the y-intercept is -1.
The slope indicates that for every increase of 1 in x, y will increase by 2. The y-intercept indicates that the line intersects the y-axis at the point (0, -1).
The equation represents a line with a positive slope that passes through the point (0, -1).
y = 2x -1
