In the xy plane , if line K has -ve slope and passes through [#permalink] New post 23 Jul 2008, 07:36
In the xy plane , if line K has -ve slope and passes through the point (-5,r) , Is the intercept of the line K positive ?

a) The slope of line K is -5.
b) r> 0

Do we have to find the y-intercept or the x-intercept since nothing is explicitly cited?
Please help to solve.

Answer is E)

Combining both the y-intercept will be some point (0, y)

y -r / 0 - (-5) = -5 => y = r - 25

so even if r>0 y can be +ve or -ve

How do we know whether we need to find the y-intercep or the x-intercept? Please helpt to clarify .... Thanks

Generally slope is referred alongwith y intercept only from eq y = mx + c.
