Answer:

1) For, m =  3/4 ,  (0,4)  , 4y - 16 - 3x = 0  is the equation of line.

2) For, m =  4 ,  (-2,-5)  , y -  4x - 4  = 0  is the equation of line.

3) For, m =  -1/3 ,  (4,-1)  , x + 3y -1  = 0  is the equation of line.

Step-by-step explanation:

If m is the slope and (x0,y0) is the point on any given equation, then

by POINT SLOPE FORMULA:

The line equation is given as (y - y0) = m (x -x0)

Now , here:

<u>1) m =  3/4 , (x0, y0) = (0.4)</u>

So,, the equation of line is (y-4) = \frac{3}{4} (x-0)\\or, 4(y-4)  =  3x

on simplification,  4y - 16 - 3x = 0  is the equation of line.

<u>2)</u><u> m =  4 , (x0, y0) = (-2.-5)</u>

So,, the equation of line is (y-(-5)) = 4 \times (x-(-2))\\or, (y+4)  =  4(x+2)

on simplification, y -  4x - 4  = 0  is the equation of line.

<u>3) m =  -1/3 , (x0, y0) = (4, -1)</u>

So,, the equation of line is (y-(-1)) = \frac{-1}{3} (x-4)\\or, 3(y+1)  =  -(x-4)

on simplification,   x + 3y -1  = 0  is the equation of line.
