Homework Help: ALGEBRA/ PLEASE HELP

Posted by CANDY on Monday, November 22, 2010 at 11:12am.

Am I correct? Find the slope and the y intercept of y = - 10/3x - 9/2. The slope is -10/3 because this is what is in front of x and the y - intercept is (0, -9/2)?

The second question is I need to find the slope of a graph that was provided for me. The y intercept is (0,6) and the second pts are (5,7). I used this formula M = y^2 - y^1/x^2-x^1
So 7 - 6 / 5 - 0 = 1 / 0. Is this slope undefined???

You're right on the first one, but the slope on the second would be 1/5 because 5-0 is 5, not zero.

If you come across a slope with the denominator of zero though, it will be undefined.
