Given two points, you can write an equation in point-slope form by first finding the slope using the two points and then plugging the slope and one point into the point-slope form equation.
Determine the point-slope form of the equation representing a line if two points on the line are (1,5) and (5,11).
Substitute in x and y values into the equation for slope.
