Answer:
1. 2/5, 2. -1. 3. 5/2, 4. 1, 5. 1/5, 6. -4/3, 7. 1/3, 8. -1/10
Step-by-step explanation:
1-3: the formula for slope is (y2 - y1)/(x2 - x1) for points (x1, y1) and (x2, y2)
1. we have points (-2, -1) and (3,1) ,plug these into the formula to get (1-(-1))/(3-(-2)) = (1+1)/(3+2) = 2/5 so the slope is 2/5
2. we have points (-3, 2) and (2, -3): (-3-2)/(2-(-3)) = -5/5 = -1
3. (-1, -2) (1,3): (3-(-2))/(1-(-1)) = 5/2
4-6: you can use the same formula
4: (1,0) (3,2): (2-0)/(3-1) = 2/2 = 1
5. (8,0) ( 13, 1) (1-0)/(13-8) = 1/5
6. (2, -1) ( 5, -5) (-5+1)/(5-2) = -4/3
7-8: slope= rise/run
7. rise=8, run=24, 8/24=1/3
8. rise=-100, run=1000, slope= -100/1000 = -1/10
