What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing variables.

Front

What does the variable 'x' represent in an equation?

Back

The variable 'x' often represents an unknown value that we are trying to solve for in an equation.

Front

What does the variable 'y' represent in an equation?

Back

The variable 'y' often represents a dependent value that changes based on the value of 'x'.

Front

How do you write an equation from a table of values?

Back

Identify the relationship between the x and y values, then express that relationship as an equation.

Front

What is the slope of a line in a graph?

Back

The slope is a measure of how steep a line is, calculated as the change in y divided by the change in x.

Front

What does it mean to plot a point on a graph?

Back

To plot a point means to mark its location on a coordinate plane using its x (horizontal) and y (vertical) values.

Front

What is the coordinate of the origin on a graph?

Back

The coordinate of the origin is (0, 0), where the x-axis and y-axis intersect.

Front

How do you identify the coordinates of a point?

Back

Coordinates are identified as (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does the equation y = x + 13 represent?

Back

This equation represents a linear relationship where for every increase in x, y increases by the same amount plus 13.

Front

What is the relationship between words typed and time in the equation w = 50m?

Back

In this equation, 'w' represents the number of words typed, and 'm' represents the minutes; Nancy types 50 words for each minute.
