Across
- 2. For any two points on a line, the rise/run or change in y/change in x. It is a measure of the steepness of a line. It is also called the rate of change of a linear function.
- 4. Replacing the variables in a algebraic expression, equation or inequality.
- 5. In a linear relationship between x and y, it tells how much y changes when x changes by 1.
- 7. An equation whose graph is a straight line.
- 8. Some quantity or elements are not finite or not countable.
Down
- 1. A linear equation in the form y=mx+b, where m is the slope and b is the y-intercept.
- 3. A technique that involves manipulating a system of equations algebraically to eliminate one of the variables, leaving only one variable to e solved.
- 4. A group of related linear equations true at the same time. A system of equations can have zero, one, or infinitely many solutions.
- 6. The y-coordinate of the point where a line, or graph of a function, intersects the y-axis.
