Please help with math!

!!!
I’ve looked every where and cannot figuire out how to answer this….I have a test today! I was absent in class the day we covered this.
Okay so: (it’s a table)
x=5 10 15
y=0.41 0.82 1.23
Need to find slope and y-intercept.
I’m really confused.
Please help me!

The slope (m) is just the difference y divided by the difference in x
So
m = (x2 - x1)/(y2 - y1)
Where x1, x2, y1, y2 are some coordinates in x and y.

So here,
m = (1.23-0.82)/(15-10) = 0.41/5 = 0.082
Each pair of coordinates from the set of three will give the same result.
