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. 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.Worksheet on standard form equation (pdf with answer key on this page's topic) Overview of different forms of a line's equation.

There are many different ways that you can express the equation of a line. There is the slope intercept form, point slope form and also this page's topic. Each one expresses the equation of a line, and each one has.

Aug 31, · write a linear equation in standard form For more math shorts go to leslutinsduphoenix.com In such cases, it may be helpful to convert the equation into a different form, the standard form. The standard form of an equation is A x + B y = C.

In this kind of equation, x . Improve your math knowledge with free questions in "Write equations in standard form" and thousands of other math skills. Writing Equations in Standard Form.

We know that equations can be written in slope intercept form or standard form.

Ax +By= C We can pretty easily translate an equation from slope intercept form into standard form. Let's look at an example. Example 1: Rewriting Equations in Standard Form. Rewrite y = 2x - 6 in standard form. The "Standard Form" for writing down a Linear Equation is Ax + By = C A shouldn't be negative, A and B shouldn't both be zero, and A, B and C should be integers.
