Since a^2 - b^2 = 1, the value of y = 1 because x=1 and 1^2 - 1^2 = 0
Answer: y = (-2/5)x - 7
This is the same as writing 
======================================================
Explanation:
Any linear equation is of the form y = mx+b, known as slope-intercept form
m = slope
b = y intercept
We'll replace m with -2/5 and replace b with -7 to get y = (-2/5)x + (-7) which simplifies to y = (-2/5)x - 7

Answer:
The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. In other words, the dependent variable is the one you measure and the independent is the one you change in an experiment.

Differentiate to find time that gradient=0
45-9.8t=0
45=9.8t
t =4.59 secs
put this value into original equation to get 103.31
