Option B:
The linear equation that best describes the model is y = 40x + 800.
Solution:
Take two points which exactly on the line.
Let the points are (0, 800) and (10, 1200).

Slope of the line:



m = 40
y-intercept of the line is where the line crosses at y-axis.
y-intercept (b) = 800
Equation of a line:
y = mx + b
y = 40x + 800
The linear equation that best describes the model is y = 40x + 800.
Option B is the correct answer.
Answer: 4
Step-by-step explanation:
Change the 2.5 to an improper fraction, then multiply by the reciprocal of 5/8.

Answer:
£225
Step-by-step explanation:
[For percentage increase, add the percentage with 100, for percentage decreases substract the percentage from 100.]
100 + 25 = 125%
× 180 = £225
