Additional comment

Your equation is easily put in the form ...

y = mx +b . . . . . line with slope m, and y-intercept b

y = 3x -1 . . . . . . line with slope 3 and y-intercept -1

In general, for a linear equation, the slope is the coefficient of x when the equation is solved for y. There are other forms of the equation for a line in which you can recognize the slope without solving for y. The point-slope form is one of those:

y -k = m(x -h) . . . . . line with slope m through point (h, k)
