For horizontal lines, that coefficient of x must be zero. In the example above, we took a given point and slope and made an equation. The point slope form gets its name because it uses a single point on the graph and the slope of the line.

We know how to use the point-slope form, so the final answer is: In the example above, you were given the slope and y-intercept. Finding the slope requires a little calculation, but it is also pretty easy. 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 axis.

First, standard form allows us to write the equations for vertical lines, which is not possible in slope-intercept form. We can move the x term to the left side by adding 2x to both sides. There are a number of reasons. Let us look at the typical parallel line problem.

Example 2 Find the equation in point-slope form for the line shown in this graph: You have a starting point on a map, and you are given a direction to head.

Example 2 demonstrates how to write an equation based on a graph.

Create the equation that describes this line in point-slope form. The variable m is the slope of the line. Try working it out on your own. And of course, if you need more help, feel free to ask the volunteers on our math help message board.

All you need to know is the slope rate and the y-intercept. Calculate the slope from the y-intercept to the second point. The following are examples of a rate: You have a positive slope. In this case it denotes a specific y value which you will plug into the equation.

I substituted the value for the slope -2 for m and the value for the y-intercept 5 for b.

The usual approach to this problem is to find the slope of the given line and then to use that slope along with the given point in the point-slope form for a linear equation.

Therefore the slope of this line is 2. Example 1 You are given the point 4,3 and a slope of 2. Find the equation for this line in point slope form. The variables x and y should always remain variables when writing a linear equation.

Remember that vertical lines have an undefined slope which is why we can not write them in slope-intercept form. Just plug the given values into your point-slope formula above. Note also that it is useful to pick a point on the axis, because one of the values will be zero.

Of course, the only values affecting the slope are A and B from the original standard form.

Locate another point that lies on the line. You have all the information you need to draw a single line on the map. What will we look for in the problem? It is simple to find a point because we just need ANY point on the line. Point-Slope Calculator Many functions to try!

Your slope was given to you, so where you see m, use 2. Write an equation in slope intercept form given the slope and y-intercept. The standard point slope formula looks like this: This example demonstrates why we ask for the leading coefficient of x to be "non-negative" instead of asking for it to be "positive".

To write the equation, we need two things:Writing Equations In Slope Intrcept Form. Showing top 8 worksheets in the category - Writing Equations In Slope Intrcept Form.

Straight-Line Equations: Slope-Intercept Form. Slope-Intercept Form Point-Slope Form Parallel, Perpendicular Lines. Purplemath.

Straight-line equations, or "linear" equations, graph as straight lines, and have simple variable expressions with no exponents on them. Write the slope-intercept form of the equation of each line.

1) 3 x − 2y = −16 2) 13 x − 11 y = −12 3) 9x − 7y = −7 4) x − 3y = 6 Writing Linear Equations Date_____ Period____ Write the slope-intercept form of the equation of each line.

1) 3 x − 2y = −16 y = 3 2 x + 8. Fill in the blanks to write an equation in slope-intercept form representing the function shown in the table.

- The slope intercept form of a linear equation has the following form where the equation is solved for y in terms of x: y = a + bx. b is the slope. a is a constant killarney10mile.com is the y intercept, the place where the line crosses the y axis. The slope intercept form equation is expressed as y = mx + c, where 'm' represents the slope of the line and 'c' represents the y-intercept of a line.

You can find the equation of a straight line based on the slope and y-intercept using this slope intercept form calculator.
