Answer:
1. Slope of 2
2. Slope of 1
3. Slope of 4/5
Explaination:
You can use the points to help you find the slope. Simply find the smallest x value and compare that to the next x value. In 1. for example, the change in x value is 2. Now do the same for the y value. In 1., the y value for the point is 0, the next being 4, so the change is 4. Now make a fraction with rise over run, or y over x, then divide. 4/2=2. So now we know 1. has a slope of 2. You can do the same for all problems.
