Front

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

Back

The slope-intercept form of a linear equation is given by the formula y = mx + b, where m is the slope and b is the y-intercept.

How can you convert a point-slope equation to slope-intercept form?

Back

To convert a point-slope equation (y - y1 = m(x - x1)) to slope-intercept form, solve for y to get y = mx + (y1 - mx1).

What is the y-intercept of a line?

Back

The y-intercept of a line is the point where the line crosses the y-axis, represented by the value b in the slope-intercept form.

Front

If a line has a slope of -3, what does this tell you about its steepness and direction?

Back

A slope of -3 indicates that the line is steep and falls from left to right.
