Question

Find the equation of a line passing through the point (-1,5) and perpendicular to the line y = -3x+4

Answer 1

Answer:

$y = 3x + 8$

Step-by-step explanation:

$let \: the \: required \: equation \: be \\ y = 3x + k \\ \\ put \: ( - 1 \: \: \: \: 5) \: in \: above \: equation \: then \\ \\ 5 = - 3 + k \\ \\ k = 8 \\ \\ therefore \: required \: equation \: becomes \: \: \\ \\ y = 3x + 8$
