# Lesson 8Point the Way Solidify Understanding

Make a graph of the function based on the following information. Then, write the explicit equation for the function.

### 1.

At , the -value is . The -value decreases by units each time increases by .

Equation:

### 2.

At , the -value is . The -value decreases by a factor of units each time increases by .

Equation:

### 3.

At , the -value is . The -value increases by a factor of times each time increases by .

Equation:

### 4.

At , the -value is . The -value increase by each time increases by .

Equation:

## Set

Use the given information to create an explicit equation. Your explicit equation should be in either slope-intercept () or point-slope form (). Use the form that is most efficient based on the given information.

### 10.

,

For each table of values, write two different explicit equations in point-slope form.

### 14.

For one of the tables in problems 11–13, show how the two equations you made in point-slope form are equivalent.

## Go

Show that the right side of the equation is equivalent to the left side of the equation. Justify each of your steps. Use the example to help guide your work.
