Answer:

#"see explanation"#

Explanation:

#"one way is to find the intercepts, that is where the graph"#
#"crosses the x and y axes"#

#• " let x = 0, in the equation for y-intercept"#

#• " let y = 0, in the equation for x-intercept"#

#x=0rArry=0-1rArry=-1larrcolor(red)"y-intercept"#

#y=0rArrx-1=0rArrx=1larrcolor(red)"x-intercept"#

#"plot the points "(0,-1)" and "(1,0)#

#"draw a straight line through them for graph"#
graph{(y-x+1)((x-0)^2+(y+1)^2-0.04)((x-1)^2+(y-0)^2-0.04)=0 [-10, 10, -5, 5]}
