what is slope of a line with example

Answer 1

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .


For example: Given two points, P = (0, –1) and Q = (4,1), on the line we can calculate the slope of the line. Let's look at a line that has a negative slope. For example: Consider the two points, R(–2, 3) and S(0, –1) on the line.

Answer 2

⭕️A straight line making an angle Φ with positive direction of x-axis .

⭕️Then tanΦ is the slope of line.

⭕️It's denoted by letter "m".

⭕️General equation for straight line will be :-
➖ax+by+c=0.

⭕️slope of the line is m = -a/b.

⭕️m=tanΦ=y2-y1/x2-x1.

✔️✔️✔️Ex:-

⭕️Take any 2 points (2,4) and (8,-9) and Φ=45°. find the slope using the formula :-

➖m=tanΦ=y2-y1/x2-x1.
