What comes into your mind when you see the word slope? We think of mountains, the roof of our houses,diagonal lines,or the slides in the playground. But what does slope really mean?

SLOPES are lines that are not in horizontal position. It has an inclined angle. A SLOPE OF A LINE refers to its steepness and direction. Here's an example...









The formula for SLOPE is:





whereas:

RISE - the difference of Ys
RUN - the difference of Xs





Here is problem #1 and it's solution







The NOTATION of the slope is m

remember our previous topic about slope intercept form?



if m = 0 that means that the slope is a horizontal line
if m > 0 that means that the line is diagonal and it rises to the right
if m is less than zerovalue and it goes downward to the right
and if m is undefined or when the fraction has a zero(0) as the denominator, that means that the line is vertical.

next example...


One more example and solution







we were asked to do ex. 7 and 8 (#5-#7)
whew!! I'm done at last!! haha.. well.. hope i did this ryt... did i?

by the way.. sorry for the graphics.. if it doesn't fit.. haha.. if i would reduce its size,, some of the writings would be very small and you wouldn't be able to read it.. so that's it..so sleepy now..

Merisa!!!

I really love your scribe!!! it's one of the best I have ever seen!!! You explained very well the topic, that is slope, and the formula for it. Your graphs aided me in doing the exercises that ms. armstrong gave us.

Your scribe really helped me in this certain pre-cal focus. Thanks!!!
