Determine `x` so that the line passing through `(3,4)a n d(x ,5)` makes an angle of`` `135^@` angle with positive direction of x-axis

Explanation

we have that the line passes `A(3,4) & B(x, 5)`

Hence, `x_{1}=3, x_{2}=x, y_{1}=4, y_{2}=5`

slope `=m=tan (1350)`

`=tan (90+45)`

`=-cot (45)`

`=-1`

`m=frac{(y_{2}-y_{1})}{x_{2}-x_{1}}`

`-1=frac{(5-4)}{(x-3)}`
