Given points A (k, 5) and B (6,8), find k so that the slope of line AB is 2/3. How do I solve this?


You plug in the slope formula just like you would if there were
a number there instead of the letter k:







You are told that the slope is  so also substitute 
that for the slope :



Do you know how to solve that for k?  If not post again asking how.

You will get:
