1/3 + 3/4= 3/12 + 9/12 =12/12 = 1circle the one mistake

The left side  1/3  does not equal to the right side  1 , which means that the given statement is false.

y= mx + b

1) line 1.

b= 1, m=1/7, y= 2/7x +1

Colored under this line, and line is solid, so    y≤ 2/7x +1.

We can modify it

7* y≤ 7*(2/7x +1),   --->   7y≤ 2x +7 or 7y-7≤2x

We have this inequality in A. and D.

2) line 2. Lets take dotted line.

y = mx + b

b= -5, m = 8/2 = 4

y = 4x -5

Colored over this line, so it is y > 4x -5. or y+5>4x

y+5>4x  Between A and D we have this inequality in D.

So, we can check D.

Answer is D, if we look at the graph.
