Linear Equation Word Problems Linear equation is an algebraic equation which may consist of a single variable and constant or product of two or more constants. It may consist of more than one variable. It can be solved for the values of the variable. By term solving linear equation, we mean that we are going to find the value of variable in the given equation.

Solving Word Problems in Algebra Writing Standard Form Equations We've studied word problems that allow for you to write an equation in slope intercept form.

How do we know when a problem should be solved using an equation written in standard form? As you are reading and analyzing the word problem, if you find that you can set up an addition problem, and you have a set total constantthen you will be able to write an equation in standard form.

Let's look at a couple of examples. Solving Word Problems Your school is sponsoring a pancake dinner to raise money for a field trip. You estimate that adults and children will attend.

Let x represent the cost of an adult ticket and y represent the cost of a child ticket. Solution First, think about what we know. This is a constant. Therefore, it will be C in your standard form equation.

We also know that in order to find our total, we need to multiply the number of people by the cost of the ticket. If we add the adult tickets and children tickets together, we will have a total.

Word Problems Are Tough! I know how difficult it is to not only learn the skill, but then to be able to apply the skill. It is hard and unfortunately, it just takes practice! If you are struggling with this concept, then check out the Algebra Class E-course. Within this E-course, you will find a lot of word problems that will not only help as you study for your tests, but that will also help you in real-life situations.

Often times, text book word problems are pretty "far out"; however Algebra Class word problems are more realistic and easy to relate to every day living.

For more information, click here. Let's look at one more example. You are running a concession stand at the basketball game. Let x represent the number of hot dogs sold and y represent the number of sodas sold.

Write an equation that can be used to determine how many hot dogs and how many sodas were sold.

Solution Think about what you know. We also have information for the price of the hot dogs and the price of the sodas. I know it's hard to imagine when you will need to use this skill, or even how to solve problems written in this form.

You will be writing these equations and solving them when you get to the Systems of Equations Unit. So, stick with me - it will all come together and make sense.Graph Sketcher: Students can create graphs of functions entered as algebraic expressions -- similar to a graphing calculator.

On a mission to transform learning through computational thinking, Shodor is dedicated to the reform and improvement of mathematics and science education through student enrichment, faculty enhancement, and interactive curriculum development at all levels.

Once you’ve got an equation entered you’d like to see, click the Graph button. Depending on the equation, you can plot the graph in 2D or 3D. Depending on the equation. Graphs of equations can have symmetry with respect to one of the coordinate axes or with respect to the origin.

equation of a circle. Figure 27 Circles From this result, you can see that the standard form of the equation of a circle with its center at the origin.

The most thing that I like about Algebrator software, is that I can save the expressions in a file, so I can save my homework on the computer, and print it for the teacher whenever he asked for it, and it looks much prettier than my hand writing.

Given the standard form equation of a circle, graph the circle. For example, graph the circle who's equation is (x+5)²+(y+2)²=4.

Primary SOL A The student will collect and analyze data, determine the equation of the curve of best fit in order to make predictions, and solve real- world problems, using mathematical models.
