Respuesta :

X+y=3. X-x+y=3 -1x. Y=-1x +3

Answer:

y=-x+3

Step-by-step explanation:

To find slope, you would want to use the formula for slope which is y=mx+b.

we are basically isolating the "y". So to find slope we would just subtract the "x" from both sides, leaving use with a negative "x" plus 3 on one side and a y on the other.
