Answer:
a.(-1,8), (2,9) b. (2,0) (3,5)
Step-by-step explanation:
a.
for (-4, 7) slope is [tex]\frac{1}{3}[/tex]
slope is m=rise /run =rise 1/run3 so to go to the next point
from (-4,7)
rise 1 so now you are at (-4,8) and run 3 and you are at (-1,8)
from (-1,8)
rise 1 to (-1, 9) and run 3 to (2,9)
b
(1,-5) slope is [tex]\frac{5}{1}[/tex]
from (1,-5) rise 5 to (1,0) and run 1 to (2,0)
from (2,0) rise 5 to (2,5) and run 1 to (3,5)
