Study Notes
Key Algebra Concepts
-
X-intercept: Points on the x-axis with a y-value of 0, representing where a graph crosses the x-axis.
-
Y-intercept: Points on the y-axis with an x-value of 0, representing where a graph crosses the y-axis.
-
Ordered Pair: The coordinates (x, y) that specify the location of a point on the coordinate plane.
-
Slope: A measure of the steepness of a line, indicating how much the line rises or falls over a horizontal distance.
-
Slope Formula: Calculated as the rise (vertical change) over the run (horizontal change), expressed as SLOPE = rise/run.
-
Slope-intercept Form: The equation of a line in the form y = mx + b, where m is the slope and b is the y-intercept.
-
X-axis: The horizontal number line used in a Cartesian coordinate system.
-
Y-axis: The vertical number line used in a Cartesian coordinate system.
-
Quadrants: The coordinate plane is divided into four sections; each quadrant corresponds to a combination of positive and negative values for x and y.
-
X-coordinate: Indicates the location along the x-axis in an ordered pair.
-
Y-coordinate: Indicates the location along the y-axis in an ordered pair.
-
Linear Equation: An equation with two variables that can be written in the form ax + b = 0, containing an infinite number of solutions.
-
Solution: Represented by a point on the coordinate plane where the equation holds true.
-
Horizontal Line: A line that runs from side to side, maintaining a constant y-value.
-
Vertical Line: A line that goes straight up and down, maintaining a constant x-value.
