Please Help MeThere Is One More Answer ChoiceD After 40 Minutes From The Dock class=

Sagot :

The vertical or y axis of the graph shows Sam's distance from the dock while the corresponding time in minutes is represented on the x axis.

The time on the x axis repesents the input. Thus, if we locate 3 on the x axis and trace it vertically to the pont where it touches the line on the graph, the corresponding value on the y axis would be 40. Hence, the correct option is C

After 3 minutes, sam is 40 meters from the dock

We can write the equation representing the function in the slope intercept form which is expressed as

y = mx + c

where

m represents slope

c represents y intercept

Slope = (y2 - y1)/(x2 - x1)

Slope = (60 - 40)/(6 - 3) = 20/3

y intercept is the point where the line cuts across the y axis. From the graph, y intercept, c = 20

By substituting into the slope intercept equation, the equation of the line is

y = 20x/3 + 20

For an input, x = 3,

y = 20 * 3/3 + 20

y = 40
