Algebra 1 Q2 Vocab

2. a collection of ordered pairs containing one object from each set.
7. Two lines or two planes that intersect at right angles
10. describes the relationship between variables
11. A line on a graph showing the general direction that a group of points seem to follow.
13. a function that represents a straight line on the coordinate plane.
14. A graph of plotted points that show the relationship between two sets of data.
15. A variable whose value does not rely on the values of other variables.
16. the equation of a straight line in the form y — y1 = m(x — x1)

1. when we have two or more linear equations working together.
3. The point at which the graphed line intersects the y-axis.
4. Lines in a plane that never meet.
5. describe a continuous response variable as a function of one or more predictor variables.
6. A set of ordered pairs (x,y) in which each value of x is paired with exactly one value of y. A function is typically represented in a table, by points on a coordinate graph, or by a rule such as an equation.
8. A variable whose value is dependent on the value of at least one other variable in a function.
9. The point at which the graphed line intersects the x-axis.
12. a function that is not a linear function.
