Writing Linear Equations

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

What does the 'm' represent in the slope-intercept form?

Back

The 'm' represents the slope of the line, indicating how steep the line is.

Front

What does the 'b' represent in the slope-intercept form?

Back

The 'b' represents the y-intercept, the point where the line crosses the y-axis.

Front

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

Back

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

Front

What is the slope of the line represented by the equation y = 4/3x - 1?

Back

The slope is 4/3.

Front

What is the y-intercept of the line represented by the equation y = 4/3x - 1?

Back

The y-intercept is -1.

Front

How do you convert the equation y = -x - 1 to slope-intercept form?

Back

It is already in slope-intercept form: y = mx + b.

Front

What is the equation of a horizontal line?

Back

y = b, where b is a constant.

Front

What is the equation of a vertical line?

Back

x = a, where a is a constant.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

The line is horizontal.
