#"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=10-9=10larrcolor(red)"y-intercept"#

#y=0rArr10-x=0rArrx=10larrcolor(red)"x-intercept"#

#"plot the points "(0,10)" and "(10,0)#

#"draw a straight line through them for graph"#
graph{(y+x-10)((x-0)^2+(y-10)^2-0.04)((x-10)^2+(y-0)^2-0.04)=0 [-40, 40, -20, 20]}
