Answer:
No becasue she only has 22 yard and the total she needs is more than 23 yards
Answer:
c
Step-by-step explanation:
Y = mx + c
If y = 4, and x = 0, then:
4 = -1 (0) + c
c = 4
If c = 4:
y = -1 (2) + 4
y = -2 +4
y = 2
If you plug in the different values of x in each equation, the answer should be:
2,0,-2
