The point slope form is defined that the difference in the y coordinate between two points (y - y1) on a line is proportional to the difference in the x coordinate points (x - x1). Enter values in point slope form calculator below to find the Equation of a straight line.
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 - y_{1} = m(x- x_{1})
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
