passes through the point (4, -2).​

Answer 1

9514 1404 393

Answer:

y = 1/2x - 4

Explanation:

The point-slope form of the equation for a line is a useful starting place when slope and point are given.

y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

y -(-2) = 1/2(x -4) . . . . line with slope 1/2 through point (4, -2)

y = 1/2x - 4 . . . . . . . . eliminate parentheses, subtract 2
