Question

draw the graph of x + Y is equal to zero and x minus Y is equal to zero X + 20 Y - 2 is equal to zero find the point of intersection of the three lines​

Answer 1

x+y=0

x minus y=0

x+20=0,y-2=0

first you take x+20=0

x= -20

similarly, take y-2=0

y=2

see the graph and draw the line in graph
