# Write an equation in standard form for the line described in letters

So let's say I have the linear equation, it's in standard form, 9X plus 16Y is equal to Associated Topics Dr.

And that is standard form. Notice also that the slope is independent of C; if you change C, you make a line parallel to the original line. Solution Now, let's look at an example that contains more than one fraction with different denominators.

Let me.

This site is wonderful! What's awkward about "standard form" is that the parameters A, B, and C do not stand for something obvious, as in the other forms.

### Slope intercept to standard form

As your example shows clearly, it is not only in "advanced mathematics" that this occurs, as I said, but in any kind of problem where, rather than one variable being presented as a function of the other, we know the value of the function and are instead interested in a linear function of BOTH variables -- in your case, the number of t-shirts and of jeans. You can algebraically manipulate from one to the other. First, we need to move the x-term to the left side of the equation so we add 3x to both sides. As you will see in the lesson below, every line can be expressed in this form. The coefficient of the x-term should be a positive integer value, so we multiply the entire equation by an integer value that will make the coefficient positive, as well as, all of the coefficeints integers.

When we talk about x-intercepts we're referring to the point where the line actually intersects the x-axis. So once again, that was pretty easy to figure out.

Writing Equations in Standard Form We know that equations can be written in slope intercept form or standard form. That's this point, that right over here. So if you start with 9X, let me do that in yellow.
