Point slope form = y - y1 = m(x- x1)

Point-slope form is about having a single point and a direction and converting that between an algebraic equation and a graph.
Point slope equation calculator Examples:
Find the equation of the line that passes through (-3, 1) with slope of 2.
x1 = -3,
y1 = 1 and
slope m = 2.


Apply Formula:
y - y1 = m(x- x1)
y-1 =2(x-(-3))
y-1 = 2(x+3)
y-1 = 2x+6
Therefore the Equation = 2x+6-y+1
Equation of the line = 2x-y+7
