slope intercept form

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, the point where the line crosses the y-axis.

Front

If the slope (m) is 2, what does this indicate about the line?

Back

A slope of 2 indicates that for every 1 unit increase in x, y increases by 2 units.

Front

How do you find the slope from 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 slope of the line represented by the equation y = -3x + 4?

Back

The slope of the line is -3.

Front

What is the y-intercept of the line represented by the equation y = 5x - 2?

Back

The y-intercept of the line is -2.

Front

Convert the equation y = 2x + 1 to slope-intercept form.

Back

The equation is already in slope-intercept form: y = 2x + 1.

Front

If a line has a slope of 0, what does this mean about the line?

Back

A slope of 0 means the line is horizontal.

Front

If a line has an undefined slope, what does this mean about the line?

Back

An undefined slope means the line is vertical.
