Compute the slope ($m$) of the line through the points $(-2,5)$ and $(4,-1)$.

Write the equation of the line in point-slope form that has slope m = 3 and passes through the point (4, −1).

Find the equation of the line through $(1,2)$ and $(4,-1)$ in slope-intercept form $y=mx+b$.

A hillside rises 150 feet over a horizontal distance of 2 miles. Using feet for both axes, compute the slope (rise/run), then write the point-slope equation for the elevation y (in feet) if the base point at horizontal position x = 0 has elevation 200 ft.

Which of the following best describes when point-slope form is preferable over slope-intercept form?
