Question

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



A.


(y + 1) = 3(x – 2)


B.


(y – 1) = 3(x + 2)


C.


(x + 2) = 3(y – 1)


D.


(x – 2) = 3(y + 1)

Answer 1

point slope form : y - y1 = m(x - x1)
slope(m) = 3
(-2,1) x1 = -2 and y1 = 1
now we sub
y - 1 = 3(x - (-2)
y - 1 = 3(x + 2)

Answer 2

thank you so much

Answer 3

its quite alright....glad I could help :)
