Writing Linear Equations

Front

What is the equation of a vertical line that passes through the point (3,−4)?

Back

x = 3

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 is the equation of a horizontal line that passes through the point (0,−3)?

Back

y = -3

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What does an undefined slope indicate about a line?

Back

The line is vertical.

Front

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

Back

The slope is 3/4.

Front

How do you convert the standard form of a linear equation to slope-intercept form?

Back

Isolate y on one side of the equation.

Front

What is the y-intercept of the line y = -1/2x - 6?

Back

The y-intercept is -6.

Front

What is the equation of a line that passes through the points (0,−8) and (0,−3)?

Back

x = 0.

Front

What is the slope of a line that is horizontal?

Back

The slope is 0.
