QuestionAnswer
Standard Form a linear equation (Ax + By = C)
X-intercept The x coordinate of a point where the graph crosses the x=ais, it occurs when y=O
Y-intercept The y coordinate of a point where the graph crosses the y-axis, it occurs when x=O
Slope the M of a nonvertical line passing through two points (x,y) and (x2, y2) is the ratio of the rise to the run.
Rise Change in y
Run Change in x
Slope intercept form The slope of a line is m, and the y-intercept of the line is b.
Constant function A linear equation written in the form y = 0x + b or y = b
Family of functions A group of functions with similar characteristics
Parent function The most common family of functions
Transformation A change in size, shape, position or orientation of a graph
Reflectiion A transformation that flips a graph over a line called the line of reflection
Translation The transformation that shifts a graph horizontally or vertically
Horizontal shrink When a > 1, the transformation is a horizontal shrink because the graph shrinks toward the y-axis
Horizontal stretch When 0 < a < 1, the transformation is a horizontal stretch because the graph stretches away from the y-axis.
Vertical Shrink When 0 < a < 1, the transformation is a vertical shrink because the graph shrinks toward the x-axis. In each chase, the x-intercept stays the same.
Vertical Stretch When a > 1, the transformation is a veritcal stretch because the graph stretches away ffrom the x-ais.
Absolute value function A function that contains an expression within absolute value symbols.
Vertex The apex/highest point
Vertex form A quadratic equation used to identify the vertex

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.
