#2x-y=1#

The equation of a straight line can be written in several forms.

#y = mx+c# is one of them.
#y = 2x-1# is in this form, therefore it is a linear equation.

It has an #x# term, a #y# term and a constant.

Re-arrange it to get standard form.

# 2x-y =1#

Other forms are:

General form: #2x-y-1 = 0#
Slope-intercept form is #y=2x-1#
