Have a play with it first move the point try different slopes. Click the blue arrow to submit. Here x 1 and y 1 is the known point whereas m is the slope of the line.
Graph y 7 -4 x 1 First plot the point x 1 y 1 which in this case is 1 7.
M and want to find other points on the line. 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. Click the blue arrow to submit. Use ym x-x1 y1 to write the equation of the line.
