From the graph we note that the points 4 0 and -4 -4 are two points on the straight line. Y - 4 8 x - 5 y - 4 8x - 40. Point slope form calculator uses coordinates of a point AxA yA A x A y A and slope m in the two- dimensional Cartesian coordinate plane and find the equation of a line that passes through A.
This form is quite useful in creating an equation of a line if youre given the slope and a point on the line.
X 1 y 1 are the point on the line m Slope of the line. From the graph we note that the points 4 0 and -4 -4 are two points on the straight line. Then the formula to find the equation of a line is y - y 1 mx - x 1. The calculator given in this section from DoMyWriting can be used to find the equation of a line when a point on the line and its slope are given.
