Question

Write an equation in point-slope form, y – y1 = m(x – x1), of the line through points (9, –2) and (10, 2). Use (9, –2) as the point (x1, y1).
a.
(y + 2) = –4(x – 9)
c.
(y + 2) = 4(x – 9)
b.
(y – 2) = 4(x + 9)
d.
(y – 2) = –4(x + 9)

Answer 1

Write an equation in point-slope form, y – y1 = m(x – x1), of the line through points (4, –4) and (1, 2). Use (4, –4) as the point (x1, y1).

Answer 2

(y+4)=-2(x-4)
