Question

.. pls help me....!!!!! Determine whether the point (-2,4) satisfy y<3x+5,y=3x+5 or y >3x+5..​

Answer 1

Given:

The point is (-2,4).

To find:

Whether the point (-2,4) satisfy
`y<3x+5,y=3x+5` or
`y >3x+5`.​

Solution:

We have a point (-2,4).

Substituting x=-2 in 3x+5 and check whether it is greater, equal or less than y value, i.e., 4.

`3x+5=3(-2)+5`

`=-6+5`

`=-1`

-1 is less than 4.

`3x+5<4`

`3x+5<y`

In can be written as

`y>3x+5`

Therefore, the given point (-2,4) satisfy
`y >3x+5`.
