Question

What is the equation in point-slope form of the line passing through (2, 5) and (−1, 8)?

y + 5 = 1(x + 2)
y + 8 = −1(x − 1)
y − 5 = −1(x − 2)
y − 8 = 1(x − 2)

Answer 1

the question you have given is wrong as the points are the answer to none of the given equations

Answer 2

(2,5)(-1,8)
slope = (8 - 5) / (-1 - 2) = 3/-3 = -1

y - y1 = m(x - x1)
slope(m) = -1
(2,5)...x1 = 2 and y1 = 5
now we sub
y - 5 = -1(x - 2) <==
