On week 13 of math 10 we’ve learned about slopes. To figure out a slope of a graph you have to find nice points. Space from one nice point to another considers slope. For example we have these graphs:
To find slope of BC we have to look at nice points and their coordinates. Our first nice point is at (1,1) and second one at (2,3) which means the graph went 2 squares up (which is y) and 1 square right (which is x).
Slope looks like this y/x so in our example it would look like: 2/1.
Next, to find a slope of AD we have to look at nice points ones again. Coordinates of first nice point are (-4,7) and of second one (0,6). We can see that graph went 1 square down (which is y) and 4 squares to the left (which is x). So our slope we look like this -1/4. The graph goes down which means it’s negative.
The slope of vertical like is undefined and the slope of horizontal line equals zero.
