# How to write a horizontal line in slope-intercept form

General Equation of a Line: Would you like to merge this question into it? MERGE already exists as an alternate of this question. Would you like to make it the primary and merge this question into it? MERGE exists and is an alternate of.

The equation of a line in the slope- intercept form is: You can use the point 5, -8 when you know the slope. If you mean points: 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.

## SparkNotes: Writing Equations: Slope-Intercept Form

Slope-intercept form is often used by teachers and school textbooks. What is the equation in slope-intercept form of the line that has a slope of 5 and y-intercept of -3? Why is it NOT possible to write the equation of the line through -8 -5 and -8 -9 in slope intercept form? Write the equation of a line in slope intercept form that has a slope of 4 and passes through the point 0 6? A line in slope-intercept form is: What is the slope of the line passing through the points of and ?

Passing through the points of and Difference between y coordinates of first and second points: Difference between x coordinates of first and second points: So, the objective is to find the equation of the line that passes through the points 2, -7 and 5, 2.

The easiest way to do this would be to use the point-slope equation:Slope Intercept Calculator finds the equation in slope intercept form! Enter 2 points or 1 point and the slope, and we'll do the rest! Chart Maker This is the equation of a vertical line. This is the equation of a horizontal line.

Two Points Slope & 1 Point First Point. x. y. Second Point. x. y. Example 3: Write an equation of the line with y-intercept 3 that is parallel to the line y = 7x - 9. Since y = 7 x - 9 is in slope-intercept form, its slope is 7. Since parallel lines have the same slope, the slope of the new line will also be 7.

To find the slope of a nonvertical line you need two know two points where the line passes through. The equation of a line in the slope- intercept form is: y = mx + b, where m is the slope and b.

Using the Point-Slope Form of a Line Another way to express the equation of a straight line. Point-slope refers to a method for graphing a linear equation on an x-y torosgazete.com graphing a linear equation, the whole idea is to take pairs of x's and y's and plot them on the graph.

Equations that are written in slope intercept form are the easiest to graph and easiest to write given the proper information. All you need to know is the slope (rate) and the y-intercept. This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept. (For a review of how this equation is used for graphing, look at slope and graphing.).
