The graph shows a trip taken by a car, where t is the time (in hours) and y is the distance
(in miles) from Phoenix.
a. Find the y-intercept of the graph. What does it represent?
b. Find the slope of the graph. What does it represent? c. How long did the trip last? d. How far from Phoenix was the car at the end of the trip?
e. Write an equation that represents the graph
Answers
Answer:
The answer is below
Step-by-step explanation:
The equation of a graph of a linear function is in the form:
y = mx + b;
where m is the slope of the graph, b is the y intercept, y and x are the variable.
Since y represent distance on y axis and t represent time on the x axis. We see that the graph passes the points:
(0, 100) and (6, 400). The equation of the graph is:
[tex]y-y_1=\frac{y_2-y_1}{t_2-t_1}(t-t_1) \\\\y-100=\frac{400-100}{6-0}(t-0)\\\\y-100= 50t\\\\y=50t+100[/tex]
a) The y intercept is 0. This means that initially the car is at 100 miles from Phoenix before the trip started. i.e. at 0 hours the distance is 100 miles.
b) The slope of the graph is 50. It means that the car traveled at a speed of 50 miles per hour
c) The end point of the graph is (6, 400), meaning the trip lasted 6 hours
d) The end point of the graph is (6, 400), meaning at the end of the trip, the car was 400 miles from Phoenix.

70 tickets per hour
We then need to find how many ticket they made in 7 hours.So: 70 x 7
=490 tickets
Answer:
490
Divide 280 by 4 to get average of 70 tickets an hour.
Multiple 70 X 7= 490

what is 2 x 1 1/2
Answers
Answer:
3
Step-by-step explanation:
2 times 1 is 2 and then multiply 1/2 by 2 and you'll get 1 then add those two numbers together and you will get 3. Note: The best way to do these types of things in multiplication is to split the numbers up among the decimal places so if you did 15 times 4 then an easy way to do it would be to split the 15 with 10 and 5 so then multiply the 10 by 4 and you get 40 now do the same to the 5 and you get 20 so now add those two numbers together and you get 60(This has nothing to do with the answer i just want to help make it easier for future problems such as this).
