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 = = -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.
