Homework Help: HELP WITH ALGEBRA!!

Posted by Margie on Wednesday, November 1, 2006 at 3:22pm.

6. What happens to the graph of the line y = 3x -2 when the equation is changed to y = 3x +6?

Look at the general equation for a straight line. It is y = mx + b where m is the slope and b is the y intercept. Therefore, the line crosses the y axis at -2 in the first equation and crosses the y axis at +6 on the other. The two lines will be parallel since they have the same slope.

Oh ok well thanx what about this one:

7. What happens to the graph of the line y = 2x - 5 when the equation is changed to y = 5x + 6?


Use the same logic. I shall be happy to critque your thoughts.

correct

Yes, the slope will be steeper AND it will crose the y axis at different places. Obviously, the two lines will not be parallel because the slopes are not the same. I hope this helps.

would it make the slope steeper?That's what I think!

find the factors
