  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

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

lockers 1, 4, 9, 16, 25, 40, and 49 are open
