Slope intercept

Front

What is the slope-intercept formula?

Back

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

Front

What does the 'm' represent in the slope-intercept formula?

Back

'm' represents the slope of the line, indicating its steepness and direction.

Front

What does the 'b' represent in the slope-intercept formula?

Back

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

Front

How do you find the slope 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 y = 2x + 3?

Back

The y-intercept is 3.

Front

What is the slope of the line represented by the equation y = -4x + 1?

Back

The slope is -4.

Front

What type of slope does a horizontal line have?

Back

A horizontal line has a slope of 0.

Front

What type of slope does a vertical line have?

Back

A vertical line has an undefined slope.

Front

If a line has a positive slope, what does that indicate about its direction?

Back

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

Front

If a line has a negative slope, what does that indicate about its direction?

Back

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