Question

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

Answer 1

`"see explanation"`

Explanation:

`"one way is to find the points where the graph crosses the"`
`"x and y axes called the intercepts"`

`• " let x = 0, in the equation for y-intercept"`

`• " let y = 0, in the equation for y-intercept"`

`x=0to0+y=-2rArry=-2`

`y=0tox+0=-2rArrx=-2`

`"plot the points "(0,-2),(-2,0)`
`"and draw a straight line through them"`
graph{-x-2 [-10, 10, -5, 5]}
