Sale price for coat =
275 x 0.85 (decimal multiplier for 15% decrease) = £233.75
£233.75 x 1.0725 (decimal multiplier for 7.25% increase) = £250.70
From the graph, we can say that the system can be represented by a linear function. A linear function has a standard form of:
y = mx + b where m is the slope and b is the y-intercept.
From the image, b would have a value of 48. The slope can be calculated as follows:
slope = ( 48 - 36 ) / (0 - 1) = -12
The equation can be written as:
y = -12x +48
or
12x + y = 48
So if H=height and Y=age then all we have to do is times the age by the amount it grows giving us 1.6y=h
