Question 735778
we are given 3x + 5y = 0

First divide both sides of the = sign by 5 

and we get

3/5 x + y = 0   and

y = -3/5 x + 0

this equation is in the form y = mx + b where m is the slope (y/x) and b = 0

now we see that if x =0 then y=0  and using the value for m (-3/5) we get the points (5, -3) and (-5, 3) are on the line that goes through the origin (0,0)

ok?
