Answer with Step-by-step explanation:
We are given that
Equation of line segment SP =

We have to find the equations of the line segments forming the 3 other sides of a rectangle.
Substitute the x=0 in given equation
Then, we get

Substitute y=0 then, we get



Hence, the equation of line segment SP passing from the point (0,3) and (-1.5,0).
By comparing withe y=mx+c
We get m=2=Slope of line segment SP
The line segment SR is perpendicular to the line segment SP and passing form the point (-1.5,0).
Slope of line segment SR=

Because when two lines are perpendicular then the relation between the slopes of two lines is given by

The equation of line segment of SR is given by

The equation of line segment SR with slope -1/2 and passing from the point (-1.5,0) is given by


Line segment RQ is parallel to SP
So,Slope of line RQ=2
Because when two lines are parallel then their slope are equal.
Line segment PQ is perpendicular to SP
Therefore, slope of PQ=

The equation of line segment PQ with slope -1/2 and passing through the point (0,3) is given by


Substitute x=0 in

Then, we get y=-0.75
The equation of line segment RQ with slope 2 parallel to SP and passing through the point (0,-0.75)is given by
