Question

The graph shows the yearly balance, in dollars, in an investment account.

Answer 1

Take 2 points

• (0,5000)
• (2,4000)

Slope:-

$\\ \rm\Rrightarrow m=\dfrac{4000-5000}{2}=-500$

Equation in point slope form

$\\ \rm\Rrightarrow y-5000=-500(x)$

$\\ \rm\Rrightarrow y=-500x+5000$

• Initial amount=y intercept=5000
