Question

What is the point slope form of a line that has a slope of 3 and passes through (1,4)

Answer 1

The equation of such a line is given by y=Ax+B where we have to determine the constants A, B. Since the slope is 3 we have that A=3 and since the line passes through the point (1,4) we must have that 4=3+B which implies that B=1. Thus, the equation of the line is y=3x+1.
