Answer:
y - 8 = x + 7
Step-by-step explanation:
To write the equation of a line use the point slope form. Substitute m = 1 and (-7,8).
![y - y_1 = m(x-x_1)\\y - 8 = 1(x --7)\\y - 8 = 1(x + 7)\\y - 8 = x+7](https://tex.z-dn.net/?f=y%20-%20y_1%20%3D%20m%28x-x_1%29%5C%5Cy%20-%208%20%3D%201%28x%20--7%29%5C%5Cy%20-%208%20%3D%201%28x%20%2B%207%29%5C%5Cy%20-%208%20%3D%20x%2B7)
Answer:
Initial height of the anchor is 75 meters.
Step-by-step explanation:
We are given the following in the question:
![l(t)=-2.4t+75](https://tex.z-dn.net/?f=l%28t%29%3D-2.4t%2B75)
where, I is the anchor's elevation in meter after t seconds dropped from the ship.
We have to find the initial height of anchor that is we have to put t = 0 in the equation.
Putting t = 0, we get,
![l(0)=-2.4(0)+75 = 75](https://tex.z-dn.net/?f=l%280%29%3D-2.4%280%29%2B75%20%3D%2075)
Thus, initial height of the anchor is 75 meters.

Answer:
Step-by-step explanation:
The house blueprint shows the bedroom is 4 in wide and its actual length is 12 yards wide. This means that every 1 inch on the blue print represents 3 yards on the actual building. The scale is the ratio of the length of a side on the blueprint to the length of a corresponding side on the actual. Therefore, the scale for the blueprint is 3: 1
Therefore, the scale factor is 3
