Question | Answer |
Equations of Horizontal and Vertical Lines | If y= constant, the graph is a horizontal line If x= constant, the graph is a vertical line |
Solution, Equation Containing two Variables | When an equation with two variables is an ordered pair that makes the equation a TRUE statement |
Substitution | A method of solving a system of equations by solving one equation to get one of the variables and substituting the result in the other equation |
X- axis and Y- axis | The two number lines |
Ordered Pair | (number, number) |
Slope | The ratio of a line rise ---- run |
System of Equations | two or more equations with the same variables |
Linear Combination or Addition- Subtraction | The result after multiplying two quantities by a constant, then adding the results |
Scale | Putting a number every 5 units on the two axes |
Graph | The point on the plane |
Quadrants | The axes divide the graph paper into four regions |
Slope of Horizontal Lines | 0 |
Slope of Vertical Lines | No slope |
Abscissa | The first number in an ordered pair |
Point - Slope form of a Linear Equation | An equation in the form y-y1=m(x-x1) The slope is m, and a fixed point on the other line is (x,y). The variables x and y stand for coordinates of a variable on the line |
Y-Intercept | The value of y when x is 0 |
X-Intercept | The value of x when y is 0 |
Slope- Intercept Form | An equation of the form y=mx+b, where m and b are constants -The constant m is the slope -The constant b is the y-intercept |
Solution of a System | An ordered pair that satisfies ALL the equations in the system |
Solution Set | The set of all solutions to an equation |
Coordinates | To gather the two numbers (number,number) which create a point in a plane |
Cartesian Coordinate System | The whole system- x-axis, y-axis, points on the plane; named after Rene Descartes |
Run | The change in x when going from one point to another on the Cartesian Coordinate System |
Rise | The change in y when going from one point to another on the Cartesian Coordinate System |
Ordinate | The second number in an ordered pair |
Simultaneous Equations | Equations in a system that can be solved at the same time |
