The spring will be stretched 18.2 inches by force of 26 pounds.
Step-by-step explanation:
7 pound stretches the spring = 4.9 inches
Ratio of force to spring = 7:4.9
New force = 26 pounds
Spring stretched = x
Ratio of new force to spring = 26:x
Using proportion;
Ratio of force to spring :: Ratio of new force to spring
Product of mean = Product of extreme
Dividing both sides by 7
The spring will be stretched 18.2 inches by force of 26 pounds.

Answer:
y = 10/9x - 46/4 <u>OR</u> y = 10/9x -15.3
Step-by-step explanation:
1. Find the slope of the points (change in y over the change in x)
(174, 178)
(165, 168)
10/9
2. Plug into y = mx + b to find the y-intercept of the equation (I am using point 165, 168)
168 = 10/9(165) + b
3. Solve
168 = 10/9(165) + b
168 = 550/3 + b
-46/3 = b <u>OR</u> -15.3 = b
3. Plug in the slope and the y-intercept into y = mx + b
y = 10/9x - 46/4 <u>OR</u> y = 10/9x -15.3
