parallel: y = -x - 1 perpendicular: y = x + 2 parallel: y = x - 1 perpendicular: y = -x + 1 parallel: y = x + 1 perpendicular: y = -x - 3 parallel: y = 2x - 2 perpendicular: y = -2x - 1

You can do this provided you understand the relationship between slopes of parallel vs perpendicular lines. Parallel lines will have the same slope (slopes are equal) Do you want to do the parallel line first?

Please hurry! I don't have much time cuz I have to go somewhere soon

O.K. we want to calculate a parallel line to y=x+5 and it goes through the point (-2,-1) (x=-2, y=-1) The slope is the coefficient of the x in the y=x+5 equation so it is 1 (positive 1). Slope is not more than the change in y divided by the change in x. Or slope = (y1-y2)/(x1-x2) For this equation 1 = (y-(-1))/(x-(-2) or|dw:1354996414474:dw| Did you follow ???

Okay!

The perpendicular is where I get messed up

Apparently you ran off. Well the perpendicula line will have a negative reciprocal of the slope of or line. That will be a -1.|dw:1354996665195:dw|
