PreAlgebra C1/C2/C3

TermDefinition
like terms Terms of an expression which have the same variables raised to the same exponents.
simplest form an algebra expression is one which has no like terms and no expression.
literal equation An equation that has two or more variables.
inequality A mathematical sentence that compares expressions.
solution of an inequality A value that makes the inequality true.
solution set The set that shows all the solutions of the inequality on a number line.
solution of a linear equation All of the points on a line that make the equation true.
slope A ratio of the change in y (the rise) to the change in x (the run) between any two points on a line. It is measure of the steepness of a line.
rise The change in y between any two points on a line.
run The change in x between any two points on a line.
x-intercept The x-coordinate of the point where a line cross the x-axis.
y-intercept The y-coordinate of the point where a line cross the y-axis
slope- intercept form A linear equation written in the form y= mx + b. The slope of the line is m, and the y-intercept of the line is b
standard form a linear equation is a + by= c, where a and b are not both zero
point-slope form A linear equation written in the form y - y1 = m(x -x1). The line passes through the point (x1, y1), and slope of the line is m.
literal expression An expression in which the exponent has one variable
graph of an equality a graph that shows all the solutions of the inequality on a number line
linear equation An equation whose graph is a line

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.
