Question

There is a line that includes the point (9,–8) and has a slope of –19. What is its equation in point-slope form?

Answer 1

y +8 = -1/9(x -9)

Explanation:

You want the point-slope form of the equation of the line through point (9, -8) with slope -1/9.

Point-slope form

The equation of the line through point (h, k) with slope m is ...

y -k = m(x -h)

You have (h, k) = (9, -8), and m = -1/9. Using these values, the equation is ...

y +8 = -1/9(x -9)
