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
Answer:
26
Step-by-step explanation:
Because DAC is a straight line we can equate that:
4x - 8 + 34 + 76 - x = 180
3x + 102 = 180
3x = 78
x = 26
The perimeter of the square is 80 yards
