If the line passing through `(4,3)a n d(2,k)` is parallel to the line `y=2x+3,` then find the value of `kdot`

Text Solution

Verified by Experts

The correct Answer is:
`-1`
The slope of line passing through (4,3) and (2,k)
`m_1=(k-3)/(2-4)=(3-k)/(2)`
The slope of the given line `y=2x+3`,
`m_2=2`
The lines are parallel. Therefore,
`(3-k)/(2)=2`
or `k=-1`
