Urgent please help .On a piece of graph paper, graph y+2<-2/3x+4

Serjik [45]

Take a look at the function $y+2=- \frac{2}{3}x+4$ . You can simplify it to $y=- \frac{2}{3}x+2$ . If x=0, then y=2 and when y=0, x=3. You obtain two points (0,2) and (3,0) that lie on the line $y+2=- \frac{2}{3}x+4$ .

Since $y+2\le - \frac{2}{3}x+4$ , the line $y+2=- \frac{2}{3}x+4$ should belong to the shaded area.

Now take point (0,0). Since $0+2\le- \frac{2}{3}\cdot 0+4$ , you can conclude that point (0,0) belongs to the shaded area.Using all these thoughts, you can make a conclusion that the correct choice is B.
