Question

How do you graph `2x-y=6` by plotting points?

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=0rArr0-y=6rArry=-6larrcolor(red)"y-intercept"`

`y=0rArr2x-0=6rArrx=3larrcolor(red)"x-intercept"`

`"plot "(0,-6)" and "(3,0)`

`"draw a straight line through them for graph"`
graph{(y-2x+6)((x-0)^2+(y+6)^2-0.04)((x-3)^2+(y-0)^2-0.04)=0 [-28.88, 28.84, -14.42, 14.46]}
