Graphing Lines Review

Front

What is the slope of the line represented by the equation y = -x + 2?

Back

The slope is -1.

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

Determine the slope and y-intercept of the equation y = 4x - 5.

Back

Slope: 4, Y-intercept: (0, -5).

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

What is the y-intercept of the line represented by the equation y = 2x + 3?

Back

The y-intercept is (0, 3).

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

If a line has a slope of 2, what does this mean?

Back

For every 1 unit increase in x, y increases by 2 units.

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 'y-intercept' refer to?

Back

The y-intercept is the point where the line crosses the y-axis.
