write the equation if the line in slope- intercept form that passes through (7,-4) with a slope of -1.

QveST [7]

9514 1404 393

Answer:

y = -x +3

Step-by-step explanation:

The point-slope form can be a useful place to start.

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

You require the line ...

y -(-4) = -1(x -7)

y = -x +7 -4 . . . . . . . . eliminate parentheses, add -4

y = -x +3 . . . . . . . . . slope-intercept form
