What is the x-intercept of a graph?

Back

The x-intercept is the point where the graph crosses the x-axis, represented as (x, 0).

Front

How do you find the slope of a line?

Back

The slope (m) is calculated as the change in y divided by the change in x (m = Δy/Δx).

Front

What is the coordinate of the origin?

Back

The origin is the point (0, 0) on a coordinate plane.

Front

What does the y-axis represent in a coordinate plane?

Back

The y-axis represents the vertical line where x = 0, moving up and down.

Front

What is the definition of a coordinate point?

Back

A coordinate point is a pair of numbers (x, y) that defines a position on a coordinate plane.

Front

How do you identify the coordinates of a point on a graph?

Back

The coordinates are identified by the horizontal (x) and vertical (y) distances from the origin.

Front

What does it mean if a slope is undefined?

Back

An undefined slope occurs when a line is vertical, meaning it does not change in the x-direction.

Front

What is the formula for the slope-intercept form of a line?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed, typically in the form y = mx + b.

Front

What is the significance of the y-intercept?

Back

The y-intercept is the point where the graph crosses the y-axis, represented as (0, b).
