PreAlgebra C1/C2/C3

TermDefinition
like terms Terms of an expression which have the same variables raised to the same exponents.
simplest form The simplest form of an algebraic expression is one which has no like terms and no parentheses.
linear expression An Algebraic expression in which the exponent of the variables is 1 .
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 of all numbers which make a mathematical statement true.
graph of an inequality A graph that shows all the solutions of the inequality on a number line.
linear equation An equation whose graph is a line.
solution of a linear equation All of the point 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 a measure of the steepness of the line .
rise The change in y between any two point on a line.
run The change in x between any two point on a line
x-intercept The x-coordinate of the point where a line crosses the x-axis
y-intercept The y-coordinate of the point where a line crosses 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 The standard form of a linear equation is ax +by=c, where a and b are not both zero
point-slope form A linear equation written in the form y-y1=(x-x1).The line passes through the point (x1,y1),and the slope of the line is m.

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.
