Question 122821: I have looked in my textbook to try to figure out how to do this but it has not helped me. i was wondering if you could explain it better:
Write each equation in stadard form using integers
1. y=4x-11
2. y=2/3x-25/3
thanks for helping

Question 123007: It contains a graph to find the constant of a slope. I know how to find the slope but not a constant, teacher is not helpful, he describes the problem so he knows it, which is not helpful to children.
The problem shows a graphy with a blue line stretching from Q2's top left corner and reaching Q4's bottom right corner. In Q4 it shows a blue dot at
(2,-2) then another blue dot at (0,0) Then it says y= -x
I cannot seem to figure this out

Question 123012: This question is from the book Hutchison, D., Bergman, B., Baratto, S., & Hoelzle, L. (2005). Beginning algebra (6th ed.). New
York: McGraw-Hill
A google search says this question has been asked before; however, went I link to the page and search I cannot find it, if it is out there I'm sorry but I can't seem to get it.
Rewrite the equation -3x+4y=11 as a function of x.
Any explanation of how to accomplish this would be so helpful. The textbook just isn't making sense to me. Thanks!

Question 123014: This question is from the book Hutchison, D., Bergman, B., Baratto, S., & Hoelzle, L. (2005). Beginning algebra (6th ed.). New
York: McGraw-Hill
I thought I had graphing down okay but this one is very confusing for me for some reason. Any help would be appreciated. Thanks!
The question is asking to graph the function (that is where I get confused)
f(x)= -2x - 5

Question 123016: This question is from the textbook Hutchison, D., Bergman, B., Baratto, S., & Hoelzle, L. (2005). Beginning algebra (6th ed.). New
York: McGraw-Hill. (I do not have the actual book so no ISBN #)
The question is asking to evaluate each function for the value specified.
f(x)=Xsquared-7x+10; find (a) f(0), (b) f(5), and (c) f(-2).
I'm sorry but I don't even know how to start this one. Any explanation of the process would be helpful and very, very appreciated. Thanks!

Question 122982: Hi, my son just started a new school on Tues. Has an Algebra worksheet that he doesn't understand. I am normally able to help him, but I do not know how to do this type of problem.
1. Determine if the graphs of the equations y=2/3 and 3x+2=6 are parallel, perpendicular or neither.
2. Write an equation for the line that is paralled to y=1/2x-1. Tell how you know they are parallel.
3. Find the slope of the lines perpendicular to the graph of 3x-y=11.
4. Write an equation of the line that passes through (5,3) and is parallel to x+3y=6.
Any help or explanations would be greatly appreciated.
