How to write an equation from a graph worksheets

Elicit from students that the reason the bonus points earned is dependent is because the points earned depends on the questions answered. Graph this situation for the students so they can then see that even if they do not have a table of all the possible values, they can use the graph to determine what their possible earned points would be based on more questions answered.

How to write an equation from a graph worksheets

Instructions for Implementing the Task This task can be implemented individually, with small groups, or with the whole class.

From Tables to Graphs and Back! -

The teacher asks the student to complete the problems on the Table to Equation worksheet. The teacher asks follow-up questions, as needed. Examples of Student Work at this Level The student cannot write a correct equation because he or she does not understand the relationship between the variables.

Questions Eliciting Thinking How are the numbers on the left side of the table related to the numbers on the right side of the table? Do you notice a pattern?

Does your pattern work for every pair of numbers in the table? Will your equation work for every input value?

Slope-Intercept Form

How can you check? Does one variable increase or decrease when the other variable increases or decreases? What is an independent variable? What is a dependent variable?

What happens to the test grade when the number correct on the test changes? Can you determine how much the grade changes for each right question? What happens to the number of diagonals when the number of sides changes?

Can you relate the amount of change in the number of sides to the change in the number of diagonals? Instructional Implications Provide the student with some completed tables of values and guide him or her to recognize trends or patterns. Have the student determine whether the value of the dependent variable increases or decreases as the value of the independent variable increases.

Then encourage the student to analyze the relationship more closely and describe the actual amount of change by referring to numerical values and operations.

Show the student how to check each row and be certain the mathematical relationship is consistent for every input value. Clarify the difference between expressions and equations. Explain to the student how the equation shows the relationship between the variables.

Guide the student to write equations to model the relationship between the variables shown by the tables.

Graph of an Equation

Examples of Student Work at this Level The student recognizes the relationship between independent and dependent variables but does not write an accurate equation. Records the operation instead of the complete equation.

Writes an expression instead of the complete equation. Questions Eliciting Thinking Can you write an equation that uses both variables?

Is this an equation? Can you turn this expression into an equation? What is the difference between an equation and an expression?

The three main ways to find slope are from a graph, two points, and in an equation." "This style of graphic organizer can be used as a summary of the whole lesson in preparation for testing. We can discuss details side by side and see how they relate.".

And that is when you're given a graph you're asked to write the equation that created that graph. A lot of the times we do it backwards. Most people are pretty good at taking an equation and drawing the graph of it here you have to do it backwards someone is going to you a graph you're going to be asked to write the equation.
