Question

Can you helpMe please the question is a 3 part question a b and c

Answer 1

(a)

In order to find the equation, let's use the slope-intercept form of the linear equation:

`V=mt+b`

Where m is the slope and b is the y-intercept.

Looking at the graph, the initial value for t = 0 is 11500, therefore the value of b is 11500.

To calculate the slope, we can use two points from the graph (let's use (0, 11500) and (1, 9500)) in the formula below:

`\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=(11500-9500)/(0-1)=(2000)/(-1)=-2000 \end{gathered}`

Therefore the equation is V = -2000t + 11500.
