Equations of Lines

Front

What is the equation of a line in slope-intercept form?

Back

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

The slope of the line.

Front

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

Back

The y-intercept of the line.

Front

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

Back

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

Front

If a line has a slope of 4, what does this indicate about the line?

Back

The line rises 4 units for every 1 unit it moves to the right.

Front

What is the slope of a line that is horizontal?

Back

0.

Front

What is the slope of a line that is vertical?

Back

Undefined.

Front

Write the equation of a line with a slope of -3/2 that passes through the point (4, -3).

Back

y = -3/2 x + 3.

Front

Find the slope of the line represented by the equation y = -5/4 x + 2.

Back
