Question

Which equation represents a line that passes through (2, –) and has a slope of 3?

Answer 1

The complete question in the attached figure

Let
(2, -R)----------> the point (2, -?)

the equation of a line is
y-y1=m*(x-x1)
point (2.-R)  and m=3
so

y+R=3*(x-2)

the answer is the option 
y + = 3(x – 2)
