Answer 1

Answer:

the question was very easy dude

pls mark it as brainliest

Step-by-step explanation:

$to \: prove \: that : \\ k - y1 = m(h - x1) \\ \\ so \: \: a \: certain \: straight \: line \: passes \\ through \: (x1,y1) \: and \: (h,k) \\ its \: slope = m \\ \\ we \: know \: that \\ slope = \frac{y2 - y1}{x2 - x1} \\ \\ accordingly \: here \\ m = \frac{k - y1}{h - x1} \\ \\ k - y1 = m(h - x1) \\ hence \: proved$
