The general form is y=mx+b
y=3x-1 <>
m = slope; b = y intercept [the point that crosses the y axis]
so the slope is 3 !!

When a line is in slope-intercept form, the slope is the coefficient of x (the number, with it's sign, multiplied to x).
The given line is not in slope-intercept form. Add 3x to both sides:
y = 3x + 1.
Now we can see by looking that the slope is 3.

All these people are right, but maybe you don't know how to put it into slope-intercept form... y=mx+b
You need to isolate y on the left side, so use inverse operations to move the -3x to the right side.
We do the opposite of -3x so we add 3x to both sides.
y -3x + 3x = 1 + 3x
y = 1 + 3x
then just rearrange to get in the order you want...
y = mx+ b
y = 3x + 1
m, slope = 3,
b, y-intercept = 1

y=mx+b, m being the slope
y-3x=1 add 3x to both sides
y=3x+1 m=3
so the slope is 3.

Using the equation of line: y=mX+c
Reform your equation in this form:
y-3x=1
y=3x+1
m is the gradient which is also the steepness of slope.
m = 3
Hence the slope of the equation is 3
