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

'm' represents the slope of the line.

Front

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

Back

'b' represents the y-intercept, the point where the line crosses the y-axis.

Front

How do you determine if a slope is positive?

Back

A slope is positive if the line rises from left to right.

Front

How do you determine if a slope is negative?

Back

A slope is negative if the line falls from left to right.

Front

What does a zero slope indicate about a line?

Back

A zero slope indicates a horizontal line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line.

Front

If a line has a slope of -3, what does this mean?

Back

It means that for every 1 unit increase in x, y decreases by 3 units.

Front

Write the slope-intercept form of a line with a slope of 2 and a y-intercept of 4.

Back

y = 2x + 4.

Front

What is the slope of the line represented by the equation y = -1/2x + 3?

Back

The slope is -1/2.
