Please give me the x and y intercepts so I can graph this:

A girl goes for a walk. She leaves home, walks 2 blocks in 5 mins at a constant speed, she forgets her keys and runs home in 1 minute . While at her door it takes her 1 minutes to find her keys and lock the door. She then walks 5 blocks in 15 minutes, and then decides to jog home. It takes her 7 minutes to jog home. Draw a graph of the girl's distance from home (in blocks) as a function of time.

b) Draw a graph for the number of blocks that the girl walked as a function of time.

Two cars enter the Florida Turnpike at Commercial Boulevard at 8:00am, each heading for Wildwood. One car's average speed is 10 miles per hour more than the other's. The faster car arrives at Wildwood at 11:00 am, 1/2 hour before the other car. What is the average speed of each car? How far did each travel?

Question 1:

Find an equation of the line containing the given pair of points. Write your answer in slope-intercept form.

(1, -5) and (5, 3)


Question 2:
Write an equation of the line described.
Through (-2, 7), perpendicular to 2x + 7y = -53



With question two with trying to find the slope I end up with;
y=-2x/7 - 53/7 and thats where I get confused

Any help would be greatly appreciated. Thanks.

The question is;

Find an equation of the line having the specified slope and containing the indicated point. Write your answer in slope-intercept form.

m = - 1/3; (11, -2)







So far I've gotten this;

y - (-2) = -1/3 ( x - 11)
y + 2 = -1/3x + 3 2/3
y = -1/3x + 3 2/3 - 2

But where do I go from there? and am I doing this correctly? Thanks.

A company is decreasing by 10 percent the amount of tuna sold in cylindrical cans. The cans will have the same height but a smalller diameter to minimize the impact on consumers when they see the smaller cans. By how much should the diameter be decreased to accomodate the change?

Could someone please explain how to do this problem. Thank you so much.

My friend gave me some brain teasers, you have to find the pattern in both of these problems.

1) 0, 4, 8, 21, 52, 65
2) 15, 26, 40, 16, 37, 58

I worked all day on these problems and feel rather confused :(
I would appreciate any help.

You are the district attorney. You face 10 court cases a year and have a $100,000 budget. In any given court case, the probability of winning is equal to X/2000, where X is the amount of the budget spent on the case. If a defendant is found guilty they must pay a fine of $2000.
a. What is the expected amount of fines the DA will collect if plea bargains are not allowed and the DA’s budget is distributed evenly among cases?

Thanks. I don't know whether I did something wrong here, but I divided 100,000/10 and I got 10,000. I then did the equation 10,000/2,000 and I got 5 for the probability, which I know is wrong because Probability isn't suppose to be greater than 1. Did I do it right? How would you approach this problem?

Just a real sort question...

Is it possible for a number to actually be infinity and if not, wouldn't saying a number is infinity actually mean it is approaching infinity?
