Question 53367: Plot points with coordinates: (2,3) (3,4) (4,5). What do you observe? Can you give
coordinates of another point with the same properties?
This is TOUGH! They gave me a graph with y at the top and x on the right side. The lines are in the form of a cross in other words and there is a graph of small squares behind this. I could not copy and paste one like it. HELP!! McGraw Hill 6th edtion. Chapter 6 Section 2, problem number 23. Thanks!!!

Question 53932: Can someone just check this to see if I am correct?? Answer in slope int. form.
A line through the points (-3,4) and (-4,6)
first I found the slope (I THINK)
6-4/-4+3= slope of -2
y-4=-2(x+3)
y-4=-2x-6
y=-2x-6+4
y=-2x-2

Question 55387: I want to thank you for any help you may provide I am having a hard time figuring this out the linear functions in these questions these qustions are not from a text book. It is approximately 480 miles from Los Angeles, California, to San Francisco, California. Allowing for various traffic conditions, a driver can average approximately 60 miles per hour.
a) How far have you traveled after 3 hours?
Answer:180 miles
Show work in this space.
3x60=180
b) How far have you traveled after 4 hours?
Answer: 240
Show work in this space.
4x60=240
c) How far have you traveled after t hours (i.e., write a linear function that expresses the distance traveled, d, as a function of time, t).
Answer:
d) How far will you HAVE LEFT to travel to reach San Francisco after you have traveled 3 hours?
Answer: 300 miles
Show work in this space.
480-180=300
e) How far will you HAVE LEFT to travel to reach San Francisco after you have traveled 4 hours?
Answer: 240
Show work in this space.
480-240=240
f) How far will you HAVE LEFT to travel to reach San Francisco after you have traveled t hours (i.e., write a linear function that expresses the distance to be traveled to reach San Francisco, s, as a function of time, t).
