Answer:
y = 3x + 62
Step-by-step explanation:
Trend line equation in the form :
y = mx + b
m = slope
b = intercept
Using the points :
(0, 62) ; (6, 80)
Slope, m = Rise / Run = (y2-y1) / (x2 - x1)
y2 = 80 ; y1= 62 ; x2 = 6 ; x1 = 0
m = (80 - 62) / (6 - 0)
m = 18 / 6
m = 3
Intercept, b = value of y when x = 0
(0, 62) ; hence, b = 62
y = 3x + b
y = 3x + 62
Answer:
Percentage change in price = 13.80%
Step-by-step explanation:
Given that:
Original price = £57.99
Decreased price = £49.99
Difference = Original price - Decreased price
Difference = 57.99 - 49.99
Difference = £8.00
Percent change = 
Percent change = 
Percent change in price = 13.80%
Hence,
Percentage change = 13.80%
