The slope of a line that passes through origin and S is 1/2, [#permalink]  26 Apr 2006, 02:30
The slope of a line that passes through origin and S is 1/2, the slope of the line that passes through (-5,0) and S is 3/2. What is the point S?

(-15/2,-15/4)

let s = (x,y)

from given data we get

y/x = 1/2

and

y/(x+5) = 3/2

by solving these 2 equations we get the point

Yes, S should be (-7.5, -3.75) from plugging in the slope equations

i agree with (-15/4, -15/2)
Just to add a bit. since s is on the line 1/2, s is multiple of it. ratio of y to x wil be 1:2, so once u solve for lets say Y we know that X should be half of it. Dont know if this is helpful.
