Can someone help and explain how you got the answer? Thanks^^

C) (0,5)

Step-by-step explanation:

f(x) is y and x is x

The table is providing you with points

y-y over x-x gives you a slope of -5

Use the points and turn it into a point-slope equation and convert to y-intercept equation

y-15=-5(x+2)

y-15=-5x-10

y=-5x+5

So the y-intercept is 5 or (0,5)

66 inches

Step-by-step explanation:

1. Yards to Feet:

1 yard= 3 feet

(6 yards)(3)= 18

6 yards = 18 feet

2. Number of Groups:

30 students/6 students per group= 5 groups

3. Total String Needed:

(5 groups)x(2.5 feet string)= 12.5 feet total string

4. Remaining String:

18 feet-12.5 feet= 5.5 feet

5. Feet to Inches:

1 foot= 12 inches

(5.5 feet)(12)= 66 inches

66 inches of string will remain
