Question

The border line of the linear inequality 4x+7y<5 is dotted. True or false

Answer 1

True

Explanation:

The region defined by the following inequality

`4x+7y<5`

is delimited by the line:
`4x+7y=5`

Therefore the points that are on the line that delimits the region are those where
`4x+7y=5`

Since the symbol "<" represents only the values that are smaller and excludes those that are greater or equal, then the points where
`4x+7y=5` are not included in the region. This is represented by drawing a dotted line
