Can someone explain what does it means when it says across the line y=-1?

campbell_st · Answer

well it is on the opposite side of the line and the same perpendicular distance from the line as the original point..

artchaos · Answer

so it would be B?

peachpi · Answer

no.(2, -4) is 3 units below the line y = -1|dw:1465504349258:dw|

elijahrich1113 · Answer

Ok so from what I read y=-1 would be a horizontal line that goes through -1

peachpi · Answer

reflecting it means moving it to 3 units above y = -1|dw:1465504455254:dw|
