Question

The slope of the line below is 5. Which of the following is the point-slope form of the line? (-1, 3)

Answer 1

y - 3 = 5(x + 1)

FROM A P E X

Explanation:

Answer 2

y - 3 = 5(x - (-1))

OR

y - 3 = 5(x + 1)

Explanation:

The point-slope form is y - y1 = m(x - x1). So plug in the coordinates (-1, 3) for y1 and x1. It should look like this, y - 3 = m(x - (-1)). Or it could also look like this, y - 3 = m(x + 1), because a negative - a negative equals a positive. Then you need to plug in the m (slope), which is 5.
