The midpoint is given as (1,7)
We are given one endpoint (-8,3) which can represent (x1,y1).
We need to get the other endpoint represented by (x2,y2)
1- The x-coordinate:
The x-coordinate of the midpoint is calculated using the following rule:
Xmidpoint = (x1+x2) / 2
1 = (-8+x2) / 2
2 = -8 + x2
x2 = 2+8
x2 = 10
The x-coordinate of Q is 10
2- The y-coordinate:
The y-coordinate of the midpoint is calculated using the following rule:
Ymidpoint = (y1+y2) / 2
7 = (3+y2) / 2
14 = 3+y2
y2 = 14-3
y2 = 11
The y-coordinate of Q is 11
Based on the above calculations, the coordinates of point Q are (10,11)

Answer:
70 units by 12 units
Step-by-step explanation:
To find the drawing size, multiply the actual dimensions by the scale factor.
(175 ft) × (2 units)/(5 ft) = (175·2/5) units = 70 units
(30 ft) × (2 units)/(5 ft) = (30·2/5) units = 12 units
The drawing size is 70 units by 12 units.
