Answer:
The answer to your question is Angelica 19, her mom = 11
Step-by-step explanation:
Data
Angelica has 8 more than her mother
total number of shoes = 30 pairs
The Number of pairs Angelica has = a = ?
The Number of pairs her mother has = m = ?
Process
1.- Write two equation that help to solve this problem
a = m + 8 Equation l
a + m = 30 Equation ll
2.- Solve the system of equations by substitution
Substitute equation l in equation ll
(m + 8) + m = 30
-Solve for m
m + 8 + m = 30
2m = 30 - 8
2m = 22
m = 22/2
m = 11
3.- Find a
a = 11 + 8
a = 19
4.- Conclusion
Angelica has 19 pairs of shoes and her mom has 11

Answer:
rate of change: 4
initial value: -1
Step-by-step explanation:
The rate of change is the number of units in the y-direction for each unit in the x-direction. As x goes from 0 to 1 (1 unit change), y goes from -1 to 3 (4 unit change). Hence the rate of change is 4.
The "initial value" is the y-value where the graph crosses the y-axis. It is -1, as we observed when computing the rate of change.
