Find and interpret the meaning of the x-intercept in this scenario.
(45, 0); the distance away from the bus stop
(27, 0); the time it takes to reach the bus stop
(45, 0); the time it takes to reach the bus stop
(27, 0); the distance away from the bus stop
Answer: LAST OPTION.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
Find the slope of the line with this formula:
Choose two points from the table and substitute the coordinates into the formula. Then, the slope is:
By definition, the line intersects the y-axis when the value of "x" is zero ().
Based on the table, the y-intercept is:
Then the equation of the line is:
The line intersects the x-axis when the value of "y" is zero (), then you can substitute these value into the equation and solve for "x":
So, you get the point:
Since the table shows the distance from the bus stop as a function of time, you can conclude that meaning of the x-intercept in this scenario is: "The distance away from the bus stop".
Answer: (27, 0); the distance away from the bus stop
