An electrician charges a fee of $\$ 45$ plus $\$ 30$ per hour. Let $y$ be the cost in dollars of using the electrician for $x$ hours. Find the slope-intercept form of the equation.
A) $y = 45 x + 30$
B) $y = 30 x + 45$
C) $y = 45 x - 30$
D) $y = 30 x - 45$

Question

Quizplus · Accepted Answer

The slope-intercept form is $y = mx + b$, where $m$ is the slope (rate per hour, \$30) and $b$ is the y-intercept (initial fee, \$45), making the correct equation $y = 30x + 45$.
