The locomotive is 40 ft long.
40 ft = 40 * 12 in. = 480 in.
The locomotive is 480 inches line.
The model is 16 inches long.
480/16 = 30
The real locomotive is 30 times longer than the model.
A window on the locomotive is 30 times wider than a window on the model.
1,400 I think :D Hope I helped!
The gradient function is
y1-y2/x1-x2
So the gradient of this line is
2-0/0-(-5)= 2/5
Recall that the linear line function is
y=mx +c ,
m is the gradient while c is the y-intercept
So, the equation of this line is
y= 2/5x + 2
