Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is .
<u>Step-by-step explanation:</u>
Here we have to Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined . Let's find out:
We know that for any two points given as slope of line is determined by :
⇒
According to question we have two points as ∴
⇒
⇒
But slope is undefined which is only possible when denominator is zero i.e.
⇒
⇒
Therefore , Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is .
