Find the slope of a line parallel to the line whose equation is 3x−y=−1. Fully simplify your answer.
To find the slope of a line parallel to the line 3x - y = -1, we need to rearrange the equation into slope-intercept form: y = 3x + 1.
The slope of the line is the coefficient of x, which is 3.
Therefore, the slope of a line parallel to the line 3x - y = -1 is also 3.
