Question

Which inequality is graphed below?

Answer 1

You can remove the second and fourth equations as possibilities because it has to be either a less than or equal to or a greater than or equal to sign in order for the line to be solid bock instead of a dashed line. You can test which sign it is by using points. Take the point (0,0) and plug it into an equation. 0?= (-1/2)*(0)+2. Simplified would be 0?=2. Because 0<= 2, the answer is y<= (-1/2)x + 2
