Question

find the equation of the line passing through points (-1,1) and (2,-4)​

Answer 1

Answer:

$equation \: of \: stright \: line \\ pssing \: through \: two \: point \\ p(a \: b) \: and \: q(c \: d)\\ \sqrt{ {( a - c)}^{2} + {(b - d)}^{2} } \\ take \: p( - 1 \: 1) \: andq(2 \: - 4) \\ \sqrt{ { - 1 - 2}^{2} + {1 + 4}^{2} } \\ \sqrt{9 + 25} \\ \sqrt{34}$
