The slope is given by
[y2 - y1] / =x2 - x1]
So
(x1 , x2) (y1, y2) =
( 8 . -3) ( 7, k)
[ k - -3] / [ 7 - 8 ] = -3 simplify
[ k + 3] / [-1] = -3 multiply both sides by -1
k + 3 = 3 subtract 3 from both sides
k = 0
For the y intercept, let x = 0...so we have...
2(0)-4y=8
0 - 4y = 8
-4y = 8 divide both sides by -4
y = -2
So.....the y intercept = (0, -2)
3(2^-2) = 3/4 = .75 inches leeway...so we have
15.25 <= d <=16.75
The second option amounts to :
2[ 1 - 2^30] / [ 1 - 2] = 2147483646 cents = $21, 474, 836.46
$2.50 / 20 = 12.5 cents per ounce
1000000000/1000000000000 = 1 / 1000
10^80 / 10^79 = 10^(80 - 79) = 10^1 = 10 times as large
