Step 1First solve for y.      5    ≥    7    +    y  Subtracting 7 from each side gives you      -    2    ≥    y  Then you graph the line, and input a value to see which way to shade. The line you graph is       y    =    -    2   , so if you input any point where       y    =    0   , no matter the x value, you will get a point above the line, because       0    &amp;gt;    -    2   .This shows that all points above the line do not work. Therefore all points below the line must work, so shade down.

Step 1Moving terms around,      5    -    7    ≥    7    -    7    +    y        y    ≤    -    2  Draw a horizontal line (not dotted)at      y    =    -    2  and continue by shading the area under it.
