Which line is perpendicular to theline -x+ y=2?
2 answers:
Answer:
y= -x+b
Step-by-step explanation:
hello :
the slope for the line : - x+y=2 is 1 because -x+y = 2 means y= 1x+2
all lines perpendicular to the line -x+y=2 have equation : y = ax+b
when : a×(1) = -1 so : a=-1
an equation is : y= -x+b
look the graph for the line : -x+y=2 (color red) and some lines
perpendicular to this line
