Standard Form of a Line by: Discussion The standard form of a line is just another way of writing the equation of a line. It gives all of the same information as the slope-intercept form that we learned about on Day 5 just written differently.

Recall that the slope-intercept form of a line is: To change this into standard form, we start by moving the x-term to the left side of the equation.

This is done by subtracting mx from both sides. 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.

This gives us the standard form: Write the equation of the line: First, we need to move the x-term to the left side of the equation so we add 3x to both sides.

Doing this gives us: Here, the coefficient of the x-term is a positive integers and all other values are integers, so we are done.

Again, start by moving the x-term to the left. Subtract 2x from both sides to get: We need the x-term to be positive, so multiply the equation by -1 to get our answer: First, we have to write the equation of a line using the given information.

Substitution gives us the equation of the line as: Now, we must convert to standard form. Finally, we must get rid of the fraction so, we clear the fraction by multiplying by the common denominator of all of the terms which is 4.

This multiplication yields the answer which is: I have seen it where fractions have been allowed to stay in standard form. In particular, our book would not have cleared the fraction in example 4. The authors would have left the answer as: However, for our class, we will clear the fractions.

It is a very useful skill that will come in handy later in the year.Slope intercept form is the more popular of the two forms for writing equations. However, you must be able to rewrite equations in both forms.

For standard form equations, just remember that the A, B, and C must be integers and A should not be negative. 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 . The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form.

When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations. By separating the two half-reactions, the energy given off by this reaction can be used to do work.

According to the first law of thermodynamics, the energy given off in a chemical reaction can be converted into heat, work, or a mixture of heat and work.

Back to top A cell is a flexible type of variable that can hold any type of variable. A cell array is simply an array of those cells.

It's somewhat confusing so let's make an analogy. A cell is like a bucket. You can throw anything you want into the bucket: a string, an integer, a double, an.

Write the equation in standard form. A linear equation is one that has no exponents greater than 1 on any variables.

To solve a linear equation in this style, you need to begin by writing it in what is called “standard form.”.
