That triangle means "delta" which means "change in". The change in y is the difference between the y coordinates; the change in x is the difference between the x coordinates. The change in y is -2-4 which is -6, and the change in x is 2-(-5) which is 7.

Answer:
1 millimeter: 1 meter
Step-by-step explanation:
we have
Part a) scale 1: 100
That means----> 1 unit on the drawing represent 100 units in the actual
Example
100 units in the actual ----> represent 100/100=1 unit on the drawing
Part b) scale 1 millimeter: 1 meter
Remember that
so
substitute
The scale is 1 millimeter: 1,000 millimeter or 1 : 1,000
That means----> 1 unit on the drawing represent 1,000 units in the actual
Example
100 units in the actual -----> represent 100/1,000=0.10 units on the drawing
Part c) scale 1 inch: 10 feet
Remember that
so
substitute
The scale is 1 inch: 120 inches or 1 : 120
That means----> 1 unit on the drawing represent 120 units in the actual
Example
100 units in the actual -----> represent 100/120=0.83 units on the drawing
therefore
The scale 1 millimeter: 1 meter would produce the smallest drawing
Each notch should equal -3 (the difference between -10 and -4 is 6), meaning that the blue dot should be -19
Y=-3/4.5-3. You can get this by plotting the points on a graph and using the rise(how far up it goes) over run(how far right) to find the Slope, then plugging in the Y-intercept.
