Question

How do you graph the equation by plotting points `y=10-x`?

Answer 1

`"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]}
