The equation of the line has the form: y = ax+b parallel to the line y = -2x + 7
=> a= -2
Passes through (4,1) => x=4, y=1
Substituting into the equation:
1= -2x(4) + b => b= 9
=> y= -2x + 9
Answer:
a
Step-by-step explanation:
it's non-linear
700% increase.
Step-by-step explanation:
The duration was 3 decades, or 30 years. The population starts at 100%, then doubles to 200% (decade 1), then 400% (decade 2), then 800% (decade 3).
800% - 100% = 700%
4 + 5 = 9
£180 / 9 = £20
£20 x 4 = £80
£20 x 5 =£100
Answer:
£80 : £100
hope it helped :)
