Answer:
x + 3y + 11 = 0 is the required equation.
Step-by-step explanation:
Here the given points are A( -2,-3) and B(4,-5)
Now, slope of the equation =
Hence, the slope of the equation is m = (-1/3)
Now, by POINT SLOPE FORMULA:
The equation of a line with slope m and point (x0, y0) is given as
(y - y0) = m (x -x0)
So, here the equation of line with (4, -5) is
or, 3y + 15 + x-4 = 0
or, x + 3y + 11 = 0
⇒ x + 3y + 11 = 0 is the required equation.
