Question

How do you find the slope and intercept of `x+y=3`?

Answer 1

`"slope "=-1," y-intercept "=3`

Explanation:

`"the equation of a line in "color(blue)"slope-intercept form"` is.

`•color(white)(x)y=mx+b`

`"where m is the slope and b the y-intercept"`

`"rearrange "x+y=3" into this form"`

`"subtract x from both sides"`

`rArry=-x+3larrcolor(blue)"in slope-intercept form"`

`"with slope "=-1" and y-intercept "=3`
