Algebra Vocabulary to Know

2. data that can contain any real number value between data points; data points can be connected.
3. how steep a line is; represented as m in the slope-intercept equation.
5. the set of all possible input (x values) of a function.
6. the set of all possible output, or y values, of a relation or function.
9. the value of x where an expression is equal to zero; this is the x-coordinate of the x-intercept of the expression's graph.
13. a change in a function that moves the function left or right.
14. the simplest equation of the linear function, y=x or f(x)=x.
16. an equation in which no variable has a power greater than 1; the general form is y=mx+b, where m is the slope and b is the y-intercept.
17. the x coordinate or coordinates where a graph intersects the x-axis, identified as (x,0).
18. having a constant rate of change between two quantities/variables and making a straight line when graphed
19. data that cannot contain the real number values between data points; data points are not connected.

1. changing a shape through movement on a coordinate plane.
4. a mathematical sentence that uses numbers, one or more operation symbols, and an equal sign.
7. moving a figure along a line for a specific distance.
8. the point on a graph of an equation where the line crosses the y-axis.
