Answer:

g(t) = aLt - aLT + L

Slope = aL

The vertical component is: L - aLT

<em></em>

Step-by-step explanation:

Given

g - L = aL(t - T)

Solving (a): Write g as a function of t

g - L = aL(t - T)

Open Bracket

g - L = aLt - aLT

Add L to both sides

g - L + L= aLt - aLT + L

g= aLt - aLT + L

Represent as s function

g(t) = aLt - aLT + L

Since the function is a function is t:

The slope is the coefficient of t;

Hence:

Slope = aL

To get the vertical intercept, we set t to 0

g(0) = aL * 0 - aLT + L

g(0) = - aLT + L

<em>Hence, the vertical component is: </em>L - aLT<em></em>
