How do you find another point on each line using slope and point given m=-3/4; passes through (0,0)?

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
