Representation of a numerical information spatially. Numbers may come from a table, situation (pattern), or rule (equation or inequality).
A horizontal line on a graph.
Analyzing a mathematical relationship to examine how the output value grows as the input value increases. Linear relationship by looking at the slope of the graph.
An equation in two variables whose graph is a line.
A graph that has a different equation for different intervals along the x-axis.
"Change in" or "Delta", Y
Vertical part of the "triangle".
A ratio that describes how steep (or flat) a line is. Can be positive, negative, or zero.
Figure that comes before Figure 1 in a tile pattern. With a graph, this is the y-intercept of the graph is the number of tiles.
A relationship in which for each input value there is one and only one output value.
"Change in" or "Delta", X
Horizontal part of the "triangle".
The point(s) where a graph intersects the x-axis.
y = mx + b
Two quantities x and y have a linear relationship, that relationship can be represented in a equation.
General equations where x and y represent the inputs and outputs of a function, other variables are often replaced with specific values.
A number multiplying a variable or product of variables.
A symbol used to represent one or more numbers.
A right triangle drawn on a graph of a line so that the "slope" of the triangle is part of the line.
The point(s) where a graph intersects the y-axis.
A rate with a denominator of one when simplified.
