None of these equations fit this line. The line is y = -1/4x
In order to find this, use the slope formula and two points. Two points that are on the line are (0, 0) and (4, -1).
m(slope) = (y2 - y1)/(x2 - x1)
m = (-1 - 0)/(4 - 0)
m = -1/4
Anything higher than 7.123
The answer is x=2. If you need help comment below
