Question

What is point slope form used for.

Answer 1

The point-slope form is useful because we can determine the equation of the line by simply knowing a single point on the line and the slope of the line.

Slope-intercept form is useful when we know the y- intercept of a line. However, we are not always given this information. When we know the slope and one point which is not the y-intercept, we can write the equation in point-slope form.

Answer 2

Point slope form is an equation to graph lines.
