How To Explain The Slope Of A Line
It is based on the slope. Lets use the examples in the last lesson.

If two points A and B lie on the line with then the slope of the line AB is given as.
How to explain the slope of a line. Slope m change in y change in x y y1 x x1. So a score difference of 15 dy would be divided by a study time of 1 hour dx which gives a slope of 151 15. Make sure that the line is straight.
Using the slope formula. If the slope is given by an integer or decimal value we can always put it over the number 1. Finding the Slope of a Line from Two Points.
In this case the line rises by the slope when it runs 1. Therefore the slope represents how much the y value changes when the x value changes by 1 unit. Plug in these values to the slope formula to find the slope.
θ lies between 0 and 180. Well use the first one to find a formula. Now well consider a vertical line such as the line x 3 x 3 shown below.
The slope of a line is the rise over the run. In this case where the line is given you can find the slope by dividing delta y by delta x. Runs 1 means that the x value increases by 1 unit.
Sometimes this is stated as the rise of the line divided by the run or the change in y values divided by the change in x values. But we cant divide by 0 0. Pick any two coordinates that the line goes through.
Starting with the slope. Well use the two points 30 3 0 and 32 3 2 to count the rise and run. The Gradient 3 3 1 So the Gradient is equal to 1 The Gradient 4 2 2 The line is steeper and so the Gradient is larger.
Get a line of which you want to know the slope. Heres the official formula. If the slope is given by an integer or decimal value we can always put it over the number 1.
Well use the letter m. Runs 1 means that the x value increases by 1 unit. The slope of a line is given as m tan θ.
The slope of a horizontal line y b y b is 0 0. Lets use the slope formula to find the slope of the line that goes through the points and. In general straight lines have slopes that are positive negative or zero.

In the equation of a straight line when the equation is written as y mx b the slope is the number m that is multiplied on the x and b is the y-intercept that is the point where the line crosses the vertical y-axis. This useful form of the line equation is sensibly named the slope-intercept form. We rearrange it like this.
Identify the values of and. Solving for Slope 1. M tan θ Where θ is the angle which the line AB makes with the positive direction of the x-axis.
Recall that the slope of a line is a measurement of how many units it goes up or down for every unit we move to the right. Pick which points coordinates are dominant in. In this lesson stu.
Coordinates are the x and y points written as x y. The slope of a line is the rise over the run. So it is just the slope formula in a different way.
