QuestionAnswer
Standard Form (p 130) Ax+By=C
X-intercept (p 131) The x-coordinate of a point where the graph crosses the x-axis. (occurs when y=0)
Y-Intercept (p 131) The y-coordinate of a point where the graph crosses the y-axis. (occurs when x=0)
Slope (p 136) "M" of a non vertical line passing through two points and is the ratio of rise to the run.
Rise (p 136) Change in y.
Run (p 136) Change in x.
Slope-Intercept Form (p 138) A linear equation written in the form y=mx+b
Constant Function (p 138) A linear equation written in the form y=0x+b or y=b
Family of Functions (p 146) A group of functions with similar characteristics.
Parent Function (p 146) The most basic function in a family of functions.
Transformation (p 146) A change in size, shape, position, or orientation of a graph.
Translation (p 146) A transformation that shifts a graph horizontally and/or vertically but does not change in size, shape, position, or orientation of the graph.
Reflection (p 147) A transformation that flips a graph over a line called the line of reflection.
Horizontal Shrink (p 148) A transformation that causes the graph of a function to shrink toward the y axis when all the x coordinates are multiplied by a factor "a" where a>1.
Horizontal Stretch (p 148) A transformation that causes the graph of a function to stretch away from the y axis when all the x coordinates are multiplied by a factor "a" where 0<a<1.
Vertical Shrink (p 148) A transformation that causes the graph of a function to shrink toward the x axis when all the y coordinates are multiplied by a factor "a" where 0<a<1
Vertical Stretch (p 148) A transformation that causes the graph of a function to stretch away from the x axis when all y coordinates are multiplied by a factor "a" where a>1
Absolute Value Function (p 156) A function that contains an absolute value expression.
Vertex (p 156) The point where a graph changes direction
Vertex Form of an absolute value function (p 158) An absolute value function written in the form f(x)=a |x-h|+ k where a does not equal 0

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
