Q15 of 169 Page 667

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

(i) (3, - 2) and ( - 5, - 7)


Slope of equation can be calculated using




Now using two point form of the equation of a line




8y + 16 = 5x - 15


5x - 8y - 16 - 15 = 0


5x - 8y - 31 = 0


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