Things I have learned this week:
-How to find the distance between two points
(1,6), (1,9)
Subtract the y values then you will get 3 or -3, since this is a distance, there is no negative values so the answer is 3.
(20,2),(5,2)
Subtract the x values and the answer is 15.
(2,5),(3,9)
Find the difference between x values and then find the difference between y values. Then use pythagorean theorem to find the length of the line segment. So the answer is
-How to find slopes
(2,5),(7,20)
You have to find the rise(difference between y values) and run(difference between x values), then do . So the answer is
REMEMBER: YOU HAVE TO DO THE SUBTRACTION IN ORDER
Important things about slopes:
positive slope: goes up from left to right
negative slope: goes down from left to right
zero slope: horizontal line
undefined: vertical line
