Answer:

y < 3x +4

Explanation:

You want the inequality that is plotted on the given graph.

Boundary line

The dashed boundary line is shown as passing through the point (-2, -2) and the y-intercept (0, 4). Its slope is ...

m = (y2 -y1)/(x2 -x1)

m = (4 -(-2))/(0 -(-2)) = 6/2 = 3

Then the slope-intercept equation of the boundary line is ...

y = mx +b . . . . . . line with slope m and y-intercept b

y = 3x +4

Shading

The shading is below the dashed line, so values of y less than those on the boundary are included in the solution set. The line itself is not included (indicated by the dashes). This means the inequality is ...

y < 3x +4
