Question

What is the point-slope form of a line with slope -3 that contains the point 10, -1

Answer 1

C.
`y + 1 = -3(x - 10)`

Explanation:

The point-slope equation of a line:

`y - y_1 = m(x - x_1)`

where m = slope, and the point is (x1, y1).

In this case, the point is (10, -1), so x1 = 10 and y1 = -1.

The slope is -3, so m = -3.

`y - (-1) = -3(x - 10)`

`y + 1 = -3(x - 10)`
