### Math Chapter 7 Vocabulary

Graph The point in the plane
X-Axis The horizontal line in a graph
Y-Axis The Vertical line in a graph
Ordered Pair The order in which the numbers occur tells which number goes with which variable. (4,7) is an ordered pair
Abscissa The first number in an ordered pair
Ordinate The second number in an ordered pair
Coordinates (4,7) are called coordinates of a plane
Cartesian Coordinate System The whole system, x-axis, y-axis, and points on a plane
Quadrants The four regions in a graph
Scale The numbers and arrows in a graph
Solution/Solution set A solution of an equation with two variables is an ordered pair that makes an equation a true statement
Y-Intercept The value of y when x is 0
X-Intercept The Value of x when y is 0
Rise + Run Is going from one point to another in a cartesian coordinate system, the run is the change in x and the rise is the change in y
Slope The slope of a line is the ratio
Slope-Intercept Form An equation of the form y=mx +b, where m and b are constants, is an slope-intercept form The constant m is the slope The constant b is the Y-Intercept
Slope of horizontal vertical lines Horizontal lines have 0 for a slope. Vertical lines do not have a slope
Point-Slope form of a linear equation An equation in the form y- y1 = m(x-x1) Is said to be in the point-slope form. THe slope is m, and a fixed point on the line is (x.y) the variables x and y stand for coordinates of a variable point on the line.
Equation of Horizontal and Vertical Lines If y = constant, the graph is a horizontal line If x = constant, the graph is a vertical line
System of Equations A system of equations is two or more equations with the same variables
Solution of a System A solution of a system of equations is n ordered pair that satisfies all the equation in the system
Substitution A method of solving a system of equations by solving one equation to get one of the variable sand substituting the result in the other equation
Simultaneous Equations Solve both equations at the same time
Linear Combination A method for solving a system of equations, A linear combination of two quantities is what you get by multiplying each quantity by a constant and adding the results.
