Answer:
Step-by-step explanation:
<u>First, find the equation of the line</u>.
<em>Slope-intercept form</em> of a linear equation:
(where m is the slope and b is the y-intercept)
From inspection of the graph, the y-intercept is at (0, -4)
Therefore, b = -4
Choose another point on the line, e.g. (7, 0)
Now use the slope formula to find the slope:
where:
Therefore, the equation of the line is:
For an inequality, the dashed line means < or > (whereas a solid line means ≤ or ≥)
As the shading is below the line, we need to use <
Therefore, the final inequality is:
