Hey there Hopire :)
To solve this, we'll use the slope given two points formula. Here it is:
y2-y1/x2-x1
Plug in the values.
6-2/9-7 =
4/2 =
2
Therefore, the slope is two, meaning 2/1 because slope is rise/run. That means that for every two you go up, you go one to the right because it's a positive slope- left for negatives.
Hope this helped!
