Question 79803: I have tried to remember how to count the points given. and I cannot could you please help me. The questions asks Two points are shown. find the slope of the line through the given points. How do I find out how many points are given. When the questions says points given do that always mean only 2 points will be given. I am totally confused please help

You probably have a whole list of exercises, and in each exercise, TWO points are given. For each exercise, then , you are given only two points. To find the slope, you must find the %28RISE%29%2F%28RUN%29+, which can be found with this famous formula:
m=%28y%5B1%5D-y%5B2%5D%29%2F%28x%5B1%5D-x%5B2%5D%29+

According to this formula, to find the RISE, you must subtract the y coordinates, and to find the RUN, you must subtract the x coordinates. Then just take the RISE OVER the RUN. That will be the slope between the two points.
