Question

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

Answer 1

y-3x=1

Explanation:

Let a point be P with coordinates (x,y)

Equation of point slope :y-y1=m(slope)*(x-x1)

y1=4,x1=1

Substituting values of x1 and y1 in the equation

y-4=3(x-1)

y-4=3x-3

y-3x=1

The equation is y-3x=1

Answer 2

y-4=3(x-1)
