Question

Write an equation in point-slope form for the line through the given point with the given slope.

(9, –1); m = 4/3


y – 9 = 4/3(x + 1)

y – 1 = 4/3(x + 9)

y – 1 = 4/3(x – 9)

y + 1 = 4/3(x – 9)

Answer 1

The correct answer is D) y + 1 = 4/3(x - 9)

In order to find this, simply take the point and the slope and plug into the base form of point-slope form.

y - y1 = m(x - x1)

Use the slope for m and the point for (x1, y1)

y + 1 = 4/3(x - 9)
