Parallel Lines and Their Slopes In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts.
The "m" stands for the slope and the "b" stands for the y-intercept. Write an equation in slope intercept form? In this form, m is the slope of the line and b isthe y intercept.
How do you find the slope intercept and standard forms of a line when the slope is undefined and you are given the coordinates 2 and 4?
When the slope is undefined, you know the line has to be vertical. Vertical lines only have an x in their equations.
When you have the coordinates 2,4 with a vertical line, the equation for the slope intercept AND standard form would be the same thing: Slope-intercept form is one way of expressing a linear function a fancy name for a straight line as an equation.
The slope-intercept form is modeled in the following way: Slope represents rate of change how much y values change in relation to x and on a graph determines how "sloped" a line is. Values of m close to 0 mean the line is more horizontal, or less sloped.
As m approaches negative infinity or positive infinity, the line becomes more vertical, or more sloped. The y-intercept is simply the coordinate where the line crosses the y-axis on a Cartesian Plane. The point is 0, b.
The slope-intercept method is popular because of its convenience. Using it, a graph of the line can be constructed very easily by hand without having to rearrange the equation.
That said, in practical applications where computer software or graphing calculators are used, the form of a linear equation is less important. Slope-intercept form is often used by teachers and school textbooks. How do you find slope-intercept form? What is slope-intercept form?
In the equation, m is the slope, and b is the y-intercept. The line crosses the y-axis at the point 0,b. The "solve for b" method This can be used if you are given two points on a line.
The line crosses the x-axis at the point 0,b. In order to find b, plug in one of the original points for x and y. In this example, we will use the point 5,1. You could use 3, - 2 if you wanted to. When we plug in the point 5,1we will get: First combine like terms: The point-slope to slope intercept method:Ask Math Questions you want answered Share your favorite Solution to a math problem Share a Story about your experiences with Math which could inspire or help others.
