Question 4

A line graph shows how far a hiker walked. The points on the graph are A(0, 0), B(1, 3), C(2, 6), and D(3, 9), where x is hours and y is miles. If the line keeps going the same way, how many miles will the hiker have walked after 5 hours? Figure: Coordinate plane with points A(0, 0), B(1, 3), C(2, 6) and D(3, 9) joined by line segments. — Coordinate plane, x from 0 to 6, y from 0 to 18; points: A (0, 0), B (1, 3), C (2, 6), D (3, 9); segments: (0, 0) to (1, 3), (1, 3) to (2, 6), (2, 6) to (3, 9)

Accepted Answer

15 miles

Question 5

Sam recorded the amount of money in his savings jar at the end of each month. Sam plots these points as (month, savings) and connects them with lines.
