Start with the point-slope formula x1 and y1 are the coordinates of a point on the line. The y2 being -7 y10 and so on with the xs. This is also known as change in y over change in x or rise over run.
Start with the slope formula.
Y m x b. Start with the slope formula. Y y 1 mx x 1 y -3 -4x 1 y 3 -4x 4. Find the equation of the line passing through the two points.
