# Write an equation in standard form given point slope form equation

A circle's equation can have either a general or standard form. If you have either the circle's center coordinates and radius length or its equation in the general form, you have the necessary tools to write the circle's equation in its standard form, simplifying any later graphing. Substitute h with the center's x-coordinate, k with its y-coordinate, and r with the circle's radius. ## Example 1: Writing an Equation Given Two Points

Slope-intercept form linear equations Standard form linear equations Point-slope form linear equations Video transcript A line passes through the points negative 3, 6 and 6, 0. Find the equation of this line in point slope form, slope intercept form, standard form.

And the way to think about these, these are just three different ways of writing the same equation. So if you give me one of them, we can manipulate it to get any of the other ones. But just so you know what these are, point slope form, let's say the point x1, y1 are, let's say that that is a point on the line.

And when someone puts this little subscript here, so if they just write an x, that means we're talking about a variable that can take on any value. If someone writes x with a subscript 1 and a y with a subscript 1, that's like saying a particular value x and a particular value of y, or a particular coordinate.

And you'll see that when we do the example.

## Linear equation

But point slope form says that, look, if I know a particular point, and if I know the slope of the line, then putting that line in point slope form would be y minus y1 is equal to m times x minus x1. So, for example, and we'll do that in this video, if the point negative 3 comma 6 is on the line, then we'd say y minus 6 is equal to m times x minus negative 3, so it'll end up becoming x plus 3.

So this is a particular x, and a particular y. It could be a negative 3 and 6. So that's point slope form. Slope intercept form is y is equal to mx plus b, where once again m is the slope, b is the y-intercept-- where does the line intersect the y-axis-- what value does y take on when x is 0?

And then standard form is the form ax plus by is equal to c, where these are just two numbers, essentially. They really don't have any interpretation directly on the graph. So let's do this, let's figure out all of these forms.

So the first thing we want to do is figure out the slope. Once we figure out the slope, then point slope form is actually very, very, very straightforward to calculate. So, just to remind ourselves, slope, which is equal to m, which is going to be equal to the change in y over the change in x.

Now what is the change in y? If we view this as our end point, if we imagine that we are going from here to that point, what is the change in y?

Well, we have our end point, which is 0, y ends up at the 0, and y was at 6. So, our finishing y point is 0, our starting y point is 6. What was our finishing x point, or x-coordinate? Our finishing x-coordinate was 6. Let me make this very clear, I don't want to confuse you. So this 0, we have that 0, that is that 0 right there. And then we have this 6, which was our starting y point, that is that 6 right there. And then we want our finishing x value-- that is that 6 right there, or that 6 right there-- and we want to subtract from that our starting x value.kcc1 Count to by ones and by tens.

kcc2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1). kcc3 Write numbers from 0 to Represent a number of objects with a written numeral (with 0 representing a count of no objects).

kcc4a When counting objects, say the number names in the standard order, pairing each object with one and only. IntroductionOver the last decade numerous accounting papers investigate the empirical relation between stock market values (or changes in values) and particular accounting numbers for the purpose of assessing or providing a basis of assessing those numbers’ use or proposed use in an accounting standard.

Different geometric shapes have their own distinct equations that aid in their graphing and solution. A circle's equation can have either a general or standard form. Point Slope Form and Standard Form of Linear Equations. Learning Objective(s) · Give the point slope and standard forms of linear equations and define their parts.

Write an equation in point-slope form for the line that passes through the given point with the slope provided. Then graph the equation. (í2, 5), slope í6. Finding the Equation of a Line Given a Point and a Slope. If we have a point,, and a slope, m, here's the formula we: use to find the equation of a line: It's called the point-slope .
