The second column is for substituting x into the equation in order to solve for y. A Few Notes About Example 3 This example has a slightly different direction, but involves the same process.

Slope Steepness and Direction The slope of a line tells two things: If you can only plant 1 pepper plant every 2 minutes, you still empty out the flat, but the rate at which you do so is lower, the absolute value of m is low, and the line is not as steep.

Teacher opens by reviewing the answers to the DN. I plotted those points on my graph. Get students to try one: Select and set the dependent and independent variables to Aask.

To find a value for y given a value for x, substitute the value for x into the expression and compute. Instructional Implications Ask the student to identify the independent and dependent variables and to verbally describe the relationship between them. Have the student explain the difference between an expression and an equation and how an equation can show the relationship between the dependent and independent variables.

There are a number of reasonable possibilities. The teacher asks the student to complete the problems on the Table to Equation worksheet. The same numbers appear as in the previous sequence, but in reverse order.

Remember, you also have a choice of positive or negative numbers! Discussion of linear characteristics lacks significant detail or is difficult to follow.

This task can provide an opportunity to discuss mathematical modeling and function fitting to bring in a real-world example one can discuss predicting sea levelsas well as the nature of scientific extrapolation and inductive reasoning versus mathematical deductive reasoning.

Two or fewer or no examples of linear functions are attempted, all are inaccurate, no sketches are provided, or no real-world examples are included. Enter two or three more values in the X column.

Lines with the Same Slope Lines with the same slope are either the same line, or parallel lines. Does one variable increase or decrease when the other variable increases or decreases?

Linear characteristics are addressed to some extent but not in detail; constant rate of change slope is mentioned but not discussed.If you want to enter a rule into the table, just write a formula on top in terms of x1. For example, x1 + 2.

If you want to get Desmos to figure out the rule, you have to use the regression feature. Write a recursive routine that will produce the number sequence in each column of the table.

c. Find the number of toothpicks, perimeter, and area of Figure 1. Complete the function table. 2. Write the rule of the function table, using words.

3. pairs to plot and label each point.

Then use a ruler and draw a segment to connect the points. 6. Compare the y-coordinate of each point to its Write the rule of the function table, using words.

3. P(t) for the appropriate cities, write the functional rule for R(t). Now that you have the two functions defined, complete the table below showing the per capita violent crime rate in both cities by year using the data from Table 1 and 2.

Have students graph at least two of their functions, write the rule for the function and write the ordered pair in a table on the graph. These can be posted or turned in for teacher Have students create a table or chart of their values and a rule that explains the relationship in the chart.

Have students decide which type of sequence each.

A function is a process or a relation that associates each element x of a set X, the domain of the function, to a single element y of another set Y (possibly the same set), the codomain of the function.

DownloadComplete each table. then write a function rule for each relationship
