#2x-3y = -2#

Explanation:

A linear equation with an #x, y# and number term represents a straight line.
It can be written in different forms:

General form: #ax +by +c =0" "larr# no fractions

Standard form: #ax +by = c" "larr# no fractions

Slope/intercept form: #y = mx +c" "larr# may have fractions

#y+4 = 2/3(x+7)" "larr" "xx 3# to get rid of the denominator

#3y +12 = 2(x+7)" "larr# multiply the bracket by 2

#3y +12 = 2x+14" "larr# re-arrange the terms

The #x# term is usually positive

#12-14 = 2x-3y#

#2x-3y = -2#
