Writing Equations of Lines

Front

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

Back

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

Front

What does 'm' represent in the equation y = mx + b?

Back

In the equation y = mx + b, 'm' represents the slope of the line.

Front

What does 'b' represent in the equation y = mx + b?

Back

In the equation y = mx + b, 'b' represents the y-intercept of the line.

Front

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

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

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

Back

The y-intercept is -4.

Front

Write the equation of the line with a slope of 2 and a y-intercept of 3.

Back

The equation is y = 2x + 3.

Front

What is the slope of a line that is horizontal?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a line that is vertical?

Back

The slope of a vertical line is undefined.

Front

Write the equation of the line that passes through the points (1, 2) and (3, 6).

Back

The equation is y = 2x.

Front

If a line has a slope of -1 and passes through the point (2, 3), what is its equation?

Back

The equation is y = -x + 5.
