Select the equation of the line that passes through the point (2, –1) and has slope 3 in point-slope form.


(y + 1) = 3(x – 2)


(y – 1) = 3(x + 2)


(x + 2) = 3(y – 1)


(x – 2) = 3(y + 1)

Answer:

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

Explanation:

from equation,

y - y1 = m( x - x1)

given x1=2, y1= -1

m = 3 (slope)

substitute

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

ans: y+1= 3(x+2)
