Answer:

The value of y is -16.

Step-by-step explanation:

To find the missing coordinate, we can use the slope equation and plug in all known values.

m(slope) = (y2 - y1)/(x2 - x1)

6 = (y - 2)/(4 - 7)

6 = (y - 2)/-3

Now we can solve using cross multiplication.

y - 2 = -3*6

y - 2 = -18

y = -16

A contractor needs to buy grass seed to cover a lawn. The dimension of the llama song below. One bag of grass seed cover isn’t i

DedPeter [7]

The minimum number of bags of seed the contractor needs to buy the to cover the entire lawn is 4

<h3>How to determine the number of bags</h3>

Start by calculating the area of the entire field using:

$Area = Length * Width$ --- area of square

So, we have:

$Area = (18 + 54 + 18)* 28$

$Area = 2520$

Next calculate the area of the porch using:

$Area = 0.5 * (L1 + L2) * H$ -- area of trapezium

So, we have:

$Area = 0.5 * (54+ (54 + 18 + 18 - 14 - 14)) * 10$

$Area = 580$

The difference between the areas of the entire field and porch is the area of the lawn.

So, we have:

$Lawn= 2520 - 580$

$Lawn= 1940$

The above means that, the area of the lawn is 1940 square yards

If one bag of grass covers 600 square yards, then the number of bags that can cover 1940 square yards is:

$n =\frac{1940}{600}$

$n =3.23$

Round to the next highest integer

$n =4$

Hence, the minimum number of bags of seed is 4 bags
