Slope Intercept & Point Slope 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 the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x; it indicates how steep the line is.

Front

How do you identify a positive slope on a graph?

Back

A positive slope rises from left to right.

Front

How do you identify a negative slope on a graph?

Back

A negative slope falls from left to right.

Front

What is the point-slope form of a linear equation?

Back

The point-slope form is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Front

What is the y-intercept of the equation y = 2x + 3?

Back

The y-intercept is 3.

Front

What is the slope of the line represented by the equation y = -4x + 2?

Back

The slope is -4.

Front

How do you convert from point-slope form to slope-intercept form?

Back

Distribute the slope and rearrange the equation to isolate y.

Front

What is the equation of a line with a slope of 0?

Back

The equation is y = b, where b is the y-value for all x.

Front

What does it mean if a line has an undefined slope?

Back

An undefined slope means the line is vertical.
