Question

How do you graph the equation by plotting points `2x – 2y = 6`?

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=0rArr-2y=6rArry=-3larrcolor(red)"y-intercept"`

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

`"Plot the points "(0,-3)" and "(3,0)`

`"Draw a straight line through them for graph"`
graph{(y-x+3)((x-0)^2+(y+3)^2-0.04)((x-3)^2+(y-0)^2-0.04)=0 [-10, 10, -5, 5]}
