Answer:
This is in the form y=mx+b . m is the slope and b is the y-intercept. In this case, the slope is 3 and the y-intercept is −1 .
X=15/7 (in exact form) or x= 2 1/7 (in mixed number form) or x= 2.142857 (in decimal form)
Answer:
To find the original dimensions, write a proportion with the scale as the first ratio and the scale dimension compared to the actual dimension as the second ratio. Use cross products to solve. To find new dimensions, write a proportion with the new scale as the first ratio and the scale dimension compared to the actual dimension as the second ratio. Use cross products to solve.

Answer:
0.336 in^2
Step-by-step explanation:
Scale down all the proportions:
14 × 0.10 = 1.4
8 × 0.10 = 0.8
3 × 0.10 = 0.3
Multiply new proportions:
1.4 × 0.8 × 0.3 = 0.336
