Really confused?!

[kristin.mauller]

This is a problem being asked in a writing/problem solving question. My classmates and I are having some issues.. Can anyone help?! Thanks!


Your text indicates that the standard form of a linear equation in two variables is

Ax + By = C
Note: Even though we are using 5 letters, only the x and y represent variables.

Note: Your book also says that both A and B cannot be equal to zero.

1. Consider the special case where the numerical value for "A" is equal to zero. NOTE* we are NOT saying that the value of x is zero**

Give a complete explanation of the special linear equation this would yield and why.

2. Consider the special case where the numerical value for "B" is equal to zero.

Give a complete explanation of the special linear equation this would yield and why.

3. The text indicates that when the x value of an ordered pair is equal to 0, the y value will be an intercept.

Give an explanation of why this occurs graphically or algebraically.

4. Finish this statement..... when the x value of an ordered pair is equal to 0, the y value is the y intercept, therefore: when the ________value of an ordered pair____.

1. Consider the special case where the numerical value for "A" is equal to zero.

Give a complete explanation of the special linear equation this would yield and why.

What did you get when you made A equal zero and graphed a few lines?

2. Consider the special case where the numerical value for "B" is equal to zero.

Give a complete explanation of the special linear equation this would yield and why.

What did you get when you made B equal zero and graphed a few lines?

3. The text indicates that when the x value of an ordered pair is equal to 0, the y value will be an intercept.

Give an explanation of why this occurs graphically or algebraically.

What did you notice when you graphed various lines and looked at where they crossed the x- and y-axes? What did you notice about the coordinates of the x-intercepts? What did you notice about the y-intercepts? What did you notice about the value(s) of x for points on the y-axis? What did you notice about the value(s) of y for points on the x-axis?

4. Finish this statement..... when the x value of an ordered pair is equal to 0, the y value is the y intercept, therefore: when the ________value of an ordered pair____.

This is not a complete statement -- there is no "is" for the second half -- so there is no way to know what they're wanting. Sorry.

Please consult with your instructor regarding the missing information. Thank you!
