Exam 2 Review Worksheet - Equations, Linear Inequalities, Absolute Value Page 7

2. How to explain how to find the x and y intercepts of a line if the equation is written in standard

form?

3. What is slope-intercept form of a line? Why do you think it is called slope-intercept form?

4. What is point-slope form of a line? Why do you think it is called point slope form?

5. How do you know if two lines are parallel? How do you know if they are perpendicular?

6. What is the slope of the line? How do you find it?

7. What is the slope of a horizontal line?

8. What is the slope of a vertical line?

Practice problems:

1. Graph the equation and indicate the slope, if it exists.

2. Find an equation for a line with slope= -3 and y intercept=7, write your answer in standard

form.

3. Find an equation for a line which passes through the point (-5,4) and m=

, write your final

answer in slope-intercept form.

4. Given the x-intercept of -4 and y-intercept of -5, find an equation for the line and write your

final answer in slope-intercept form.

5. Write an equation of the line that contains the point (-3,4) and is parallel to

6. Write an equation of the line that contains the point (-2,4) and is perpendicular to

Chapter 3, Section 1

Do you know:

1. Is every correspondence between two sets a function? Why or why not?

2. What are the four different ways that we represented functions?

3. Can you explain what the domain and range of a function are?

4. What do the terms “input” and “output” refer to when working with functions?

5. How can we tell if an equation defines a function by looking at the graph of the equation?

Practice Problems:

1. Look in your book at page 171-172 numbers 7-24. Can you identify which ones are functions

and which are not. Also, which are one-to-one? Why are they one-to-one?

2. Page 173 numbers 27-34.
