Answer:

#"x-intercept "=4," y-intercept "=4/5#

Explanation:

#"to obtain 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=4-0=4larrcolor(red)"y-intercept"#

#y=0rArr4-5x=0#

#rArr-5x=-4rArrx=(-4)/(-5)=4/5larrcolor(red)"x-intercept"#
graph{(y-4+5x)((x-0)^2+(y-4)^2-0.04)((x-4/5)^2+(y-0)^2-0.04)=0 [-10, 10, -5, 5]}
