Students use concepts of proportionality to explore, develop, and communicate mathematical relationships. Write the slope intercept form of the equation with the values that you found for m and b.

The student applies mathematical process standards to develop an understanding of proportional relationships in problem situations. In their groups they need to compare answers and come to a consensus on the correct slope-intercept equation and graph.

For additional information, email rules tea. This is easy to prove by plotting a graph from a table of values that you can easily create for both forms of the equations. In that case, you can see that this revised equation is now: Note that data from a catalog can be notoriously inaccurate.

Once again, this form of the equation produces the exact same line as the original form given in the question, despite it appearing to be different. The student applies mathematical process standards to develop concepts of expressions and equations.

Please share in the comments! Therefore, from the y-intercept, we will count down 1 and right 3. There are four pieces of information that you need to find out from the catalog. We'll even convert your presentations and slide shows into the universal Flash format with all their original multimedia glory, including animation, 2D and 3D transition effects, embedded music or other audio, or even video embedded in slides.

The student applies mathematical process standards to represent and use rational numbers in a variety of forms. Any point on that line is a solution to the equation.

And, best of all, most of its cool features are free and easy to use. In this example, we will graph an equation that has a negative slope.

Students will use a problem-solving model that incorporates analyzing given information, formulating a plan or strategy, determining a solution, justifying the solution, and evaluating the problem-solving process and the reasonableness of the solution.

In this case, A is 5, B is -1, and C is No problem, just check out the following video. The student applies mathematical process standards to use geometry to solve problems. Thanks for reading, Christina. Students connect verbal, numeric, graphic, and symbolic representations of relationships, including equations and inequalities.

For the case of several simultaneous linear equations, see System of linear equations. There is truly something for everyone!

You have to be very accurate in plotting your points and drawing your lines in order to be able to read your graph to find other solutions! The Catalog Data Input window is designed to make sense of this information. Middle School Statutory Authority: This article considers the case of a single equation with coefficients from the field of real numbersfor which one studies the real solutions.

The student applies mathematical process standards to use numerical or graphical representations to analyze problems. Additional features v 3. The case of just one variable is of particular importance, and it is frequent that the term linear equation refers implicitly to this particular case, in which the name unknown for the variable is sensibly used.Write the equation in the form y=mx+b and identify m Find the equation of the line graphed below.

Write the equation in the form y=mx+b and identify m and b. Determining the Equation of a Line From a Graph. Determine the equation of each line in slope intercept form. Checking Your Answers. Click "Show Answer" underneath the problem to see the answer.

Or click the "Show Answers" button at the bottom of the page to see all the answers at once. A straight line which has a slope of 0 is a horizontal line. Therefore the x value has no effect on the line at all, The y value will always be In standard form: #y = mx +c# This becomes #y = 0x.

Show transcribed image text Find the equation of the line graphed below.

Write the equation in the form y = mx + b and identify m and b. Write the equation in the form y = mx + b and identify m and b.

To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope.

This is the value of m in the equation. Next, find the coordinates of the y -intercept--this should be of the form (0, b). Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use: Step 1: Choose a point on the line, such as (2, 5).3/5(4).
