NarutoandSasuke:

i don't think it's B...

Comerpickles:

Okie, how would I solve this?

NarutoandSasuke:

Ask shadow, he's better @ this than me

Shadow:

The slopes are perpendicular

NarutoandSasuke:

^^^

Comerpickles:

Oh

Shadow:

Perpendicular lines are ones that are opposite and reciprocal of each other. 4 and -1/4 are the slopes. The reciprocal of 4 is 1/4. The opposite sign of 4 is negative. Therefore, -1/4 is the perpendicular slope of 4. Thus, they are best defined as being perpendicular to each other.
