Question

Write an equation in point slope form given: slope, m, = 2/7 and point (4, -1).

A. y + 1 = -(2/7)(x – 4)
B. y + 1 = (2/7)(x – 4)
C. y – 1 = (2/7)(x – 4)
D. y – 1 = -(2/7)(x – 4)

Answer 1

only the middle two have the correct slope, so ignore 1 and 4

Answer 2

you write
\[y-y_1=m(x-x_1)\] puttin \(m=\frac{2}{7}, x_1=4, y_1=-1\)

Answer 3

thank you! (:
