Answer:
0
Explanation:
To find slope you need to take two points from the line and use the slope formula (
)
Im going to take the points (0,3) and (-2,3) So now lets put these coordinates into the formula:

this would give us 0
(Edit* tbh i think the line might not even exist - ya know it says ¨Find the slope of the line if it exists¨ anyway ~_~ hope this helped...!)
