Answer:
a)
The equation of the straight line CD is
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given points are A (-4,0) and B( 0,3)
Slope of the line
Slope of the line
<u><em>Step(ii):-</em></u>
The equation of the straight line passing through the point ( -4,0) and having slope
y - y₁ = m(x-x₁)
The equation of the straight line AB is
<u><em> Step(iii):-</em></u>
CD is parallel to the line AB
The equation of the straight line AB is
4 y = 3 x + 12
3x - 4y +12 =0
The equation of the Parallel line is 3 x -4y +k=0
Passes through the point ( 0,3)
-12 +k=0
k =12
The equation of the Parallel line is 3 x -4y +12=0
4 y = 3 x+12
The equation of the straight line CD is
