#### 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+5=5larrcolor(red)"y-intercept"#

#y=0rArr2x+5=0rArrx=-5/2larrcolor(red)"x-intercept"#

#"plot the points "(0,5)" and "(-5/2,0)#

#"draw a straight line through them for graph"#

graph{(y-2x-5)((x-0)^2+(y-5)^2-0.04)((x+5/2)^2+(y-0)^2-0.04)=0 [-10, 10, -4, 6]}
