To solve for inequality based of the graph, one must first identify the equation of the line using the equation y = mx+b by identifying two points at (0,1) and (4,0) then find the slope using the formula: m = (y2-y1)/(x2-x1) = rise/run
m = (0-1)/(4-0)
m = -1/4 then the y-int, b when x is zero that is 1, so the equation of the line should be:
y = -1/4x + 1, the shaded area facing up indicates that y > -1/4x + 1
the answer is d
