Question

Choose the correct equation in point-slope form for the line that passes through the point with the given slope. (2, -1), m= -3

A) y - 2 = -1 [x -(-3)]

B) y + 1 = 3x - 6

C) y - 1 = -3x- 6

D) y - 1= -3x + 2

E) y + 1 = -3(x - 2)

Answer 1

y - y1 = m(x - x1)
slope(m) = -3
(2,-1)...x1 = 2 and y1 = -1
now we sub....pay attention to ur signs
y - (-1) = -3(x - 2)....not done yet
y + 1 = -3(x - 2) <===
