Answer:

y = (-4/3)(x +4) +4

Explanation:

Between the given points, the "rise" is -8 and the "run" is 6. The rise/run ratio is then -8/6 = -4/3. So, a version of the point-slope equation can be written:

y = m(x -h) +k . . . . . . . line with slope m through point (h, k)

y = (-4/3)(x +4) +4

_____

Comment on the answer

The image asks for "an equation", which seems to allow for any equation format. The equation shown above can be put into other forms.

y -4 = -4/3(x +4) . . . . different point-slope form

y = -4/3x -4/3 . . . . . . slope-intercept form

4x +3y = -4 . . . . . . . . standard form

4x +3y +4 = 0 . . . . . . general form

x/(-1) +y/(-4/3) = 1 . . . . intercept form
