slope of a straight line

Slope of a line

Process to find the slope of a line:

• We can take any two point on a line.
• Find the vertical change or change in y coordinate.
• Find the horizontal change or change in x coordinate.
• Find the ratio of these changes i.e. m = rise/run

Slope = change in coordinate y / change in x coordinate

We have basically 4 types of slopes. These are:

Zero Slope: In this case the line is parallel to the x axis, The value of x is change or increased, the value of y remains constant or unchanged.
Positive Slope: In this case as the values of x increase, the value of y is also increased and the slope of a line is positive.
Negative Slope: In this case as the values of x increase, the value of y is decreased and the slope of a line is negative.
No slope: In this case the line is parallel to the y axis, The value of y is change or increased, the value of x remains constant or unchanged.

Positive Negative Integers

Positive and Negative Integers

"The Integers" is a part of real numbers.

The Integer is a whole number, i.e. if the number is greater than 0 (zero) called the Positve Integers and those numbers less than zero called the Negative Integers. Zero is neither positive nor negative.

For every Positive Integer, there's exist a Negative Integer whihc is equal distance from the origin (0).
Two integers that lie the same distance from the origin and located in opposite directions from the orign are called the opposites. For example, "positive 9" (+9) is the opposite of "negative 9." (-9).
