Q15 of 169 Page 667

Find the slope and the equation of the line passing through the points:

( - 1, 1) and (2, - 4)


The slope of the equation can be calculated using




Now using two point form of the equation of a line




3y - 3 + 5x + 5 = 0


5x + 3y + 2 = 0


So, required equation of line is 5x - 8y - 31 = 0.
