1. Math Vocabulary
Mrs Knight

2. Axis
it’s a line and it can be either X or Y on a grid. X is the independent variable and Y is the dependent variable.

3. Coordinate Plane
it’s the plane that is formed when the X and Y axis intercept

4. Variable
it’s a quantity that changes or that can have different amounts

5. Independent Variable
it’s a quantity that stands alone (EXAMPLE: ‘time’, it doesn’t need anything else to exist)

6. Dependent Variable
it’s a quantity that changes but in order to change it needs help (EXAMPLE: ‘money’, in order to make money you need to work)

7. Ordered Pair or Coordinate Pair
it’s a point formed by the X and Y axis.

8. Origin
it’s the point where the X and Y axis intercept

9. Y intercept
it’s where the line crosses the Y axis

10. Linear relationship
it’s when the change is constant and repeats, on a graph it would be a line (EXAMPLE : Every month the seventh grader makes $10.00 babysitting)

11. Slope
it’s the inclination or steepness of a line

12. Equation of a Line
y = mx + b
m is the slope
b is the y- intercept
