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.
(x – 2) = 3(y + 1)

C.
(y – 1) = 3(x + 2)

D.
(x + 2) = 3(y – 1)

Answer 1

Answer 2

Equation line in slope popint form is given as;

y-y1=m(x-x1)

here x1=2 , y1=-1 and slope m=3
Now plugging these values in the above eqution we find
y-(-1)=3(x-2)
i.e. y+1=3(x-2)

Thus option A. (y + 1) = 3(x – 2) is the correct answer.
