Question

For the following inequality, indicate whether the boundary line should be dashed or solid. x + y < 2

dashed

solid

Answer 1

dashed

Explanation:

Answer 2

Answer: First option is correct.

Explanation:

Since we have given that

The inequality as follows :

`x+y<2`

There are two conditions to show the boundary lines:

1) Dashed line

2) Solid line

If the equation is
`ax+by\leq c` then, the boundary line should be solid since the inequality hold equal sign too.

If the equation is
`ax+by<c`, then the boundary line should be dashed since there is given strictly inequality.

So, in our case we have given that

`x+y<2`

There is no equality, so the boundary line should be dashed.

Hence, First option is correct.
