Respuesta :

f(x) is written in mx + b form for linear equation. so we have m =2 and b =  -1
m represents the slope so the slope is 2

Answer is 2
In order to solve this, you would need to know what the slope-intercept form of a line is. 
The formula is:
Y=mx + b
All your line equations must be converted to this form before solving
The M stands for slope
The B is your y-intercept
In this case, your slope is 2 and the y intercept is -1
