Then we can write our equation. And of course, if you need more help, feel free to ask the volunteers on our math help message board. Writing Linear Equations Given Slope and a Point When you are given a real world problem that must be solved, you could be given numerous aspects of the equation.

We know how to use the point-slope form, so the final answer is: Create the equation that describes this line in point-slope form. In this case it denotes a specific y value which you will plug into the equation.

Write a linear equation that can be used to determine the cost of a cab ride to anywhere around Washington DC.

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.

Find the equation for this line in point slope form. I know that this is a rate and therefore, is also the slope. Example 2 Find the equation in point-slope form for the line shown in this graph: We also now know the y-intercept bwhich is 9 because we just solved for b.

You have a starting point on a map, and you are given a direction to head. You have all the information you need to draw a single line on the map.

Now we know the slope m is -2 because that was given to us.

It is just one method to writing an equation for a line. The slope is going to be your "rate" and the point will be two numbers that are related in some way.

As you can see, point-slope form is nothing too complicated. Note also that it is useful to pick a point on the axis, because one of the values will be zero. Writing Equations Given Slope and a Point Write the equation of a line, in slope intercept form, that passes through the point 6, -3 with a slope of You have enough information to find the y-intercept, but it requires a few more steps.

Point-Slope Calculator Many functions to try! Finding the slope requires a little calculation, but it is also pretty easy.

We can now write our equation! To write the equation, we need two things: Now you are ready to solve real world problems given two points.

Point-slope form is all about having a single point and a direction slope and converting that between an algebraic equation and a graph. It is simple to find a point because we just need ANY point on the line. Just plug the given values into your point-slope formula above. Point-slope form is also used to take a graph and find the equation of that particular line.

We know the slope and a point x,y. You have all the information you need, and you can create your graph or write an equation in slope intercept form very easily. Then you will solve for b. Now we know the slope m is 1.

While you could plot several points by just plugging in values of x, the point-slope form makes the whole process simpler.

The point slope form gets its name because it uses a single point on the graph and the slope of the line. Your final result should look like: Although you have the slope, you need the y-intercept.

You must always know the slope m and the y-intercept b.Point slope method is one such method used to find the straight line equation when one co-ordinate and slope is given. Use the online analytical point slope form calculator to find the equation of the straight line using the Point-Slope Method.

Straight-Line Equations: Slope-Intercept Form. Slope-Intercept Form Point-Slope Form Parallel, Perpendicular Lines. and you will have to come up with the equation of the line. How do you do that? You plug in whatever they give you, and solve for whatever you need, like this: in giving me a point on the line, they have given me an x.

Aug 29, · How to Find the Equation of a Line. To find the equation of a line, you have some options to choose from depending on what you are given. You will ultimately always need at least one point on the line and the slope to calculate an Views: K. Find the Equation of a Line Given That You Know a Point on the Line And Its Slope The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

If you a point that a line passes through, and its slope, this page will show you how to find the equation of the line. Writing Linear Equations Given Slope and a Point.

When you are given a real world problem that must be solved, you could be given numerous aspects of the equation. If you are given slope and the y-intercept, then you have it made. You have all the information you need, and you can create your graph or write an equation in slope intercept form.

In the last lesson, I showed you how to get the equation of a line given a point and a slope using the formula Anytime we need to get the equation of a line, Let's find the equation of the line that passes through the points.

This one's a two-stepper STEP 1: Find the slope. continue. 1 2. Lines. What's the Slope of a Line?
