what is the importance of chemistry and slopes of chemisrty explain
Answers
Answer:
Chemistry is important because everything you do is chemistry! Even your body is made of chemicals. Chemical reactions occur when you breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything.
Slope gradient is important because it influences the rate at which runoff flows on the soil surface and erodes the soil. Slope shape (straight, concave, or convex) and slope length are also important properties of soil surfaces. In soil evaluation, two stakes will be set up to indicate where slope is to be determined.

Answer:
Slope =
rise
run
and m=
y2−y1
x2−x1
where m=slope and (x1,y1) and (x2,y2) are two points on the line.
y=mx+b
m=slope (x,y)=a point on the line b=the y value of the y-intercept
Identify slope from a graph
In math, slope is used to describe the steepness and direction of lines. By just looking at the graph of a line, you can learn some things about its slope, especially relative to other lines graphed on the same coordinate plane. Consider the graphs of the three lines shown below:
Three different lines on a graph. Line A is tilted upward. Line B is sharply titled upward. Line C is sharply tilted downward.
First, let’s look at lines A and B. If you imagined these lines to be hills, you would say that line B is steeper than line A. Line B has a greater slope than line A.
Next, notice that lines A and B slant up as you move from left to right. We say these two lines have a positive slope. Line C slants down from left to right. Line C has a negative slope. Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: Slope =
rise
run
.
A line that crosses the points (2,1) and (6,3). A blue line labeled Rise goes up two units from the point (2,1). A red line labeled Run goes left from the point (6,3) so that it forms a triangle with the main line and the Rise line. A formula says slope equals rise over run.
You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.
