If a line passes through the given point (x1, y1) and has a slope m, the point-slope form of the equation of the line is y – y1 = m(x – x1).
Ex) Write an equation of a line that has a slope of –2 and passes through the point (4,2).
Ex)Write an equation of the line with a slope of -½ and passes through the point
(-4,-2)
Ex) Write an equation of the line that passes through the given points (6,1) and (-4,-4)
