A moving firm charges a flat fee of $\$ 45$ plus $\$ 40$ per hour. Let $y$ be the cost in dollars of using the moving firm for $x$ hours. Find the slope-intercept form of the equation.
A) $y = 40 x - 45$
B) $y = 45 x + 40$
C) $y = 40 x + 45$
D) $y = 45 x - 40$

Question

Quizplus · Accepted Answer

The slope-intercept form of the equation is $y = mx + b$, where $m$ is the slope (rate per hour, \$40) and $b$ is the y-intercept (flat fee, \$45). Therefore, the correct equation is $y = 40x + 45$.
