Lines m and p are perpendicular. if the slope of line m is -3 what is the slope of line p
ivann1987 [24]
For two lines to be perpendicular, their slopes must be negative reciprocals of one another, mathematically:

m1*m2=-1, in this case our reference line has a slope of -3 so:

-3m=-1  divide both sides by -3

m=-1/-3

m=1/3

So the perpendicular line will have a slope of 1/3

Which ordered pair is a solution of the equation y equals x minus 3
Rom4ik [11]
Y = x-3

Basically you just need to plug in an x value and solve for y
y = x - 3
y = (4) - 3
y = 1

In this case, the ordered pair of this equation would be (4, 1)

You can do this given any x or y coordinate

Hope this helps
