Point 1#-> (x,y)-> (-3, 2 1/4)#

Point 2#->(x,y)->(+3,-2 1/4)#

Explanation:

Standard form for a straight line is #y=mx+c#

We are constrained by two parameters (conditions)

If both lines pass through the point #P->(x,y)->(0,0)#

The slope #m=-3/4#.

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The given conditions within context of the question implies that there is only one line and that it passes through the given point.

So given condition #P->(x,y)->(0,0)#

#=> y=mx+c" "->" "0=m(0)+c#

This means that #c=0# so our equation becomes:

#y=mx#

We are told that #m=-3/4#

So we now have:

#y= -3/4x# as our equation.

All we have to do now is substitute value for #x# and calculate the related value for #y#
