🗑
|
||||
| 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.
🗑
