-4x and divide by 2

-4x +y = 2

-4x      y
--- + --- = 1
  2        2


-2x      y
--- + --- = 1 ; this is called the intercept form of a line
  1        2

when x=0; y=2
when y=0;x=-1/2

y intercept is the x=0 axis; (0,2)

anonymous · Answer

y intercept set x = 0 and solve for y with your eyeballs. 
y = 2

amistre64 · Answer

the intercept form doesnt get alot of publicity does it :) http://www.mathwords.com/t/two_intercept_form_for_the_equation_of_a_line.htm

amistre64 · Answer

it prolly more for thos:

ax +by = c equations
