Review: Graphing Lines and Points

Front

What is the slope of the line represented by the equation y = 1/2x?

Back

The slope is 1/2.

Front

What is the y-intercept of the line represented by the equation y = 1/2x?

Back

The y-intercept is 0.

Front

How do you convert the equation -x + 4y = 11 to slope-intercept form?

Back

Add x to both sides to get 4y = x + 11, then divide by 4.

Front

What is the slope-intercept form of the equation -x + 4y = 11?

Back

y = 1/4x + 11/4.

Front

In the ordered pair (4,9), what does the number 4 represent?

Back

The x-coordinate.

Front

In the ordered pair (4,9), what does the number 9 represent?

Back

The y-coordinate.

Front

What does the coordinate (4, -6) indicate on a graph?

Back

It indicates a point located 4 units right and 6 units down from the origin.

Front

What is the location of point C if it is represented by the coordinate (1,0)?

Back

Point C is located 1 unit right on the x-axis.

Front

What is the general form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.

Front

What does the term 'coordinate plane' refer to?

Back

A two-dimensional surface formed by the intersection of a vertical y-axis and a horizontal x-axis.
