 Question 18406: Why is it true that any two points satisfying a linear equation will give you the same graph for the line represented by the equation? Click here to see answer by MelanieBCC(40)

 Question 18388: Here is my question: If the lines 3x + Ky = 2 and 6x - 5y - 1 = 0 are parallel, what is the value of K? I figured out that the slope of 6x - 5y - 1 = 0 is 6/5 and know that the slope is the same for the other equation since they are parallel, but I don't know how to apply it to the 1st equation.

 Question 18604: All through the chapter in my algebra class, I have not understood the standard form of a line: Ax+By=C. I only understand slope intercept form: Y=mx+b. Could you please explain how to put the information that is given about a line ( the slope, x intercept, and y intercept)into standard form. Thank you! Click here to see answer by mmm4444bot(95)

 Question 18617: has an x-intercept of 2 and is perpendicular to the graph of 5x-3y=2 Click here to see answer by venugopalramana(3286)

 Question 18624: Alright, this one is starting to become an irritation at another board. 3a ÷ 3b = x a = 10, b = 2 Now, I solve this by satisfying the variable terms first, as such: (3 * 10) ÷ (3 * 2) = x (30) ÷ (6) = x 5 = x The alternate solution that's being argued is that variable terms aren't solved first, and linear order of operations takes precedent: 3a ÷ 3b = x 3 * 10 ÷ 3 * 2 = x 30 ÷ 3 * 2 = x 10 * 2 = x 20 = x So, which is correct? I've scoured Google for this, but haven't found any confirmation either way. Click here to see answer by venugopalramana(3286)

 Question 18951: I have been unable to solve the following: -10 = 1/2x + x Is the answer 20/2? Click here to see answer by Alwayscheerful(414)

 Question 18960: I need to write this equation x+(1/y)=7 in standard form ax+by=c where all fractions are cleared and "a" is not negative. I tried multiplying each term by "y" but I ended up with xy +1=7y then xy-7y=-1 which does not make much sense. Thanks for your help! Click here to see answer by mmm4444bot(95)
