Answer:
y < (-4/3)x +5
Step-by-step explanation:
The two marked points tell you the "rise" is -4 for a "run" of 3. That is the slope of the line is ...
m = rise/run = -4/3
The line crosses the y-axis at y=5, so the y-intercept (b) is 5. Then the equation of the boundary line in slope-intercept form is ...
y = mx + b
y = (-4/3)x + 5
The shading is below the dashed line, so only y-values less than those on the line will satisfy the inequality:
y < (-4/3)x +5
