Step-by-step explanation:
Point slope form:
The equation of line is given by: .....[1]
where m is the slope and a line contains a point .
As per the given statement:
Slope(m) = 3
. = (2, 1)
Substitute these in [1] we have;
therefore, the point slope form of a line with slope 3 that contains the point (2, 1) is;
it is B
