Use the chosen point in conjunction with the slope. Simplify the formula to get a slope of ⅓. In Maths the equation of a line can be written using the point-slope form.
Substitute the slope for m in the slope intercept form of the equation.
Y 2x b. With the points plugged in the formula looks like 3 - 2 4 - 1. The calculator also has the ability to provide step by step solutions. Y - y_1 mx - x_1 The variable m stands in for the slope of the line and x 1and y 1are the x and y coordinates respectively of the point you know.
