Slope-Intercept Form

Front

What is the y-intercept?

Back

The y-intercept is the point where the line crosses the y-axis. In the equation y = mx + b, it is represented by b.

Front

What letter represents the slope of a line in the equation y = mx + b?

Back

The letter 'm' represents the slope of the line.

Front

What do the variables x and y represent in the equation y = mx + b?

Back

The variables x and y represent any point on the line.

Front

Write the equation of the line with a slope of 3/5 and a y-intercept of -1.

Back

y = 3/5x - 1

Front

Write the equation of the line with a slope of 1/3 and a y-intercept of -2.

Back

y = 1/3x - 2

Front

What is the slope in the equation y = 2x + 4?

Back

The slope is 2.

Front

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

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

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.
