O A. After 60 minutes, Sam is 6 meters from the dock.
O B. After 6 minutes, Sam is 6 meters from the dock.
C. After 60 minutes, Sam is 60 meters from the dock.
After 6 minutes, Sam is 60 meters from the dock
Correct option is D.
A straight line is an infinitely long line with no curves. A straight line can also be formed between two points, but the ends will be infinite. A straight line is a figure formed by connecting two points A (x1, y1) and B (x2, y2) with the shortest distance and extending both ends to infinity.
General formula for a straight line:
The general equation for straight lines is given as ax + by + c = 0.
a, b, c are constants and
x,y are variables.
Slope is -a/b
Given,
Graph of Distance to time is represented by an straight line
By the graph,
Line crosses from (0,20) and (3,40)
Equation of the line
y - y₁ = ((y₂ - y₁)/(x₂ - x₁))(x-x₁)
y - 20 = ((40 - 20)/(3 - 0))(x-0)
y - 20 = (20/3)(x)
y - 20 = 20x/3
y = 20x/3 + 20
Input x = 6
y = 20(6)/3 + 20
y = 120/3 + 20
y = 40 + 20
y = 60
When time = 6 minutes, distance between Sam and the dock is 60 meters.
Hence, Sam is 60 meters away from the dock after 6 minutes

Answer:
After 60 minutes, Sam is 6 meters from the dock
Step-by-step explanation:
I looked at the number line and met up where 60 minutes was.
x = -2 and decreasing from x = -2 to x = 10.
B. The graph crosses the y-axis at -8,0), increasing from * = -10 to
x = -2 and decreasing from x = -2 to x = 10
C. The graph crosses the y-axis at (0,7), increasing from x = -10 to
x = -2 and remaining constant from x = -2 to x = 10.
D. The graph crosses the y-axis at (0,7), increasing from x= -10 to
X = 0 and decreasing from x = 0 to x = 10
