Answer:

[tex]2[/tex]

Step-by-step explanation:

[tex]-2x+2y=4[/tex]

To find the y-intercept, the equation must be in the format of [tex]y=mx+b[/tex], in which [tex]b[/tex] is representative of the y-intercept.

Start by adding [tex]2x[/tex] to both sides of the equation:

[tex]2y=2x+4[/tex]

Divide both sides of the equation by the coefficient of [tex]y[/tex], which is [tex]2[/tex]:

[tex]y=x+2[/tex]

[tex]b=2[/tex]

Therefore, the y-intercept of the line is 2.
