Solve the problem. Write all linear equations in slope-intercept form.
-A house was purchased for $\$ 84,000$. After 7 years the value of the house was $\$ 147,000$. Find a linear equation that models the value of the house after $x$ years.
A) $y = 147,000$
B) $y = 7 x + 84,000$
C) $\mathrm { y } = 9000 \mathrm { x }$
D) $y = 9000 x + 84,000$

The slope ($m$) of the line is calculated by the change in value over the years, which is $(147,000 - 84,000) / 7 = 9,000$. The y-intercept ($b$) is the initial value, $84,000$. Thus, the equation is $y = 9000x + 84,000$.
