y-intercept is given, (0, 2).
x-intercept is given, ( -1/2, 0).
slope, 2%2F%28-%28-1%2F2%29%29=4.



y-2=4%2Ax%2B2
y-2=4x%2B2

            The  "solution"  and the  "answer"  by  @josgarithmetic are both   TOTALLY  WRONG.

            For your safety,  simply ignore it . . .

            I came to bring the correct solution.


y-intercept is  (0, 2).

x-intercept is  ( -1/2, 0).

The slope  m =  2%2F%28%28-1%2F2%29%29 = -4.



The equation is 

    y-2 = (-4)*(x-0)

or

    y-2 = -4x,        (point-slope form)

or, equivalently,

    y = -4x + 2       (slope intercept form).

Solved.

@josgarithmetic, since your equation is INCORRECT even after your fixing, make it EASIER:


        EITHER delete all your writing, OR accurately cross every line by red (which is PREFERABLE) . . .

    @josgarithmetic is a legendary person at this forum.


    (almost) Every problem he does touch, he converts into a TRASH -- instead of making a brilliant peace of art from it, 

    as every qualified tutor must do.


    He is as far from to be a tutor as the Earth is from a heaven.

FYI: The SLOPE is neither - 1 nor 1, as the other person says. In addition, the y-intercept is NOT + 4.
So, saying that it's either will result in a WRONG equation.
You can just DUMP this answer: cross%28highlight%28y=x%2B4%29%29 and this one: cross%28highlight%28y=4x%2B4%29%29
