LINR 2 | Lesson 3 | Check your Solution

Recall that our line could also be represented by \[y=\frac{2}{3}x+2\]
Set up an inequality that uses this form of the line and verify your result.

Recall, dividing through an inequality by a negative changes the orientation of the symbol

Use test points to verify!

Try \((-2, 4)\), when you plug it in you get a $\mathrm{false\; statement}$

$\mathrm{Try\; \backslash (1,\; 3),\; when\; you\; plug\; it\; in\; you\; get\; a\; true\; statement.}$

$\mathrm{Therefore\; the\; student’s\; shading\; is\; wrong.}$
