Answer:

Step-by-step explanation:
To find slope using two points you need to find the difference in x and y. You use 
So, 2-0=2 and 5-(-4)=9. Therefore the slope is 2/9x
If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate.
