Question

How do you graph the line `x+y=-4`?

Answer 1

`"see explanation"`

Explanation:

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

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

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

`x=0to0+y=-4rArry=-4larrcolor(red)" y-intercept"`

`y=0tox+0=-4rArrx=-4larrcolor(red)" x-intercept"`

`"plot these 2 points and draw a straight line through them"`
