How to use slope
by Krysta Vue
What is slope?
Slope is the equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis
Where can you use slope?
From learning slope in math you can almost use it anywhere such as measuring rooftops on houses, or when making a layout of a building you can use slope also. Slope is used almost everywhere!
There are many different types of slope

SLOPE!
How can i make slope into something fun?
Think about this... when skiing or snow boarding your going down hill which can also refer to a negative slope. When riding a lift to snow board, the steepness of a mountain increases, you can relate that as a positive slope. When the steepness of a mountain tends to dial down which means that your ride is almost over that can refer to an undefined slope , and there you have it! You can have fun with slope in so many different ways.
Reviewing what slope is...
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m. The direction of a line is either increasing, decreasing, horizontal or vertical. A line is increasing if it goes up from left to right.
How slope is used in the world today!
Surfing!
Slope is used in surfing as the wave goes and decreases into a negative slope as you see in this picture of the man.

Kite Skiing
Before launching off kite skiing takes off on a flat surface which can also be indicated as undefined or zero slope.

Sergeant Floyd Monument
when building the Sergeant Floyd Monument the creator had to plan out the structure. As you can see there are angles at the top going negative and positive directions of slope and on the sides its and undefined slope line.
