Solve any the three sub-questions:

Find the equation of the line passing through the points (4,-5) and (-1,-2).

Equation of line passing through points (x1,y1) and (x2,y2) is given by

Here (x1,y1) = (4,-5) and (x2,y2) = (-1,-2)


Equation of line passing through (4,-5) and (-1,-2) is given by




∴ (-3)(x-4) = 5(y + 5)


∴ - 3x + 12 = 5y + 25


∴ 12 – 25 = 5y + 3x


∴ 3x + 5y = - 13


∴ 3x + 5y + 13 = 0


Therefore equation of line passing through (4,-5) and (-1,-2) is 3x + 5y + 13 = 0
