If we observe the line it passes through x=3.5 when y=0 and when x=0, the line cuts the y axis at 7 so x intercept is 3.5 and y intercept is 7 Equation of a line with x intercept a and y intercept b \[\frac{x}{a}+\frac{y}{b}=1\] so The equation for the given line \[\frac{x}{3.5}+\frac{y}{7}=1\] multiply both sides by 7 we get \[2x+y=7\] now We need to find the inequality for the shaded region Let's assume the inequality as \[2x+y>7\] in the shaded region 0,0 is a point, let's check if it satisfies this \[0+0>7\] this is false so the answer is \[2x+y<7\]
