Question

Write the equation of a line with the slope of -3 and through the point (2,-2).

Answer 1

y +2 = -3(x -2)

Explanation:

The point-slope form of the equation of a line is useful for this:

y -k = m(x -h) . . . for a line of slope m through point (h, k)

__

y +2 = -3(x -2) . . . . fill in the given values. Note that -(-2) = +2
