Plz help I’m taking a Unit test

The relationship is rise over run (slope). In your case, it's 4/3 because you go from one point to the next by going up 4 and to the right 3. 4/3=1.3. Your slope is 1.33.

Explanation:

If you go up or to the right, that number is possitive

If you go down or to the left, that number is negative.

i.e.: Down one to the right 2. -1/2 (-0.33).

1.3 is your slope and it touches the y axis at 0, so y=1.3x+0
