Question 51131: Aqueducts were once used to carry water from rivers using gravity. Water flowing too quickly might damage an aqueduct, but water flowing too slowly might not keep the aquiducts clear. One of the best and most common designs for an aqueduct was to raise it 3 meters for every kilometer in length. What is the slope of an aqueduct built with this design?
I need help in understanding how to find the slope from this word problem because I don't understand anything about word problems. So if you could please help me to solve this problem step by step it would be helpful.

Question 51160: iam not sure if this is linear and graphs or whatever! because my worksheet is mixed so i cant tell the difference, i think they are functions okay it says here that iam supposed to identify if this is a function or not and to state if it is discrete or continuous...i have no idea wat iam doing... this is the problem ((7,8)(7,5)(7,2)(7,-1))
please help me out and explain it i got like a whole lot of these

Question 51208This question is from textbook Beginning Algebra
: Please help solve: #39. 5t+3+2t-6t=4+12
#45. 5/7x + 1/3 = 2/5 - 2/7x + 2/5
#55. -2(8p+2)-3(2-7p)-2(4+2p)=0
#58.9(2m-3)-4(5+3m)-5(4+m)+-3
I'm also having difficulty retaining the rules of multiplication, subtraction, addition and division. So many rules to remember before I'm able to tackle problems with mixed signs as well. Any tricks to remember them?This question is from textbook Beginning Algebra

Question 51216: i would really like someone to help me with this problem i have tried to do it but im not having much luck...
NAme the slope of the line and the y intercept
2x+3y+32=0
i tried to subtract 2x from everything but i came out with 1xy+32=0 and that didnt make sense then i tried to change the signs and i got something else funny looking but i really need someone to explain it to me better than my teacher she is a good teacher but i dont understand her....
thanks

Question 51250: Driving down a mountain, Tom finds that he has descended 1800 ft in elevation by the time he is 3.25 mi horizontally away from the top of the mountain. Find the slope of his descent to the nearest hundredth.
I thought that the first step would be to create an equation
y= 3.25x + 1800
But I need to find the slope, which requires 2 points (y2-y1 over x2-x1).
I am not sure what formula I shoudl start with to arrive at the slope, as requested.

Question 51246: Could someone help me with this problem: Determine the equation of the line that has a slope of 1 and passes through the point (2,-6). Write the equation in slope intercept form. The book that I use isnt very explanitory about solving these problems. I have tried to work the problems myself and I am not having much luck with them. Any help at all would be greatly appretiated. Thanks.

Question 51292This question is from textbook beginning algebra
: i have done this problem several times...each i do it i get a different answer!i'm not sure if i'm supposed to type out the problem so i will...
negative one fourth (x-12) plus one half (x+2)=x+4
i know i'm supposed to multiply everything by the LCD, which i believe is 4?
well, i hope you can help..
