A cable TV company charges $\$ 24$ for the basic service plus $\$ 8$ for each movie channel. Let y be the total cost in dollars of subscribing to cable TV, using $x$ movie channels. Find the slope-intercept form of the equation.
A) $y = 24 x + 8$
B) $y = 24 x - 8$
C) $y = 8 x + 24$
D) $y = 8 x - 24$

The slope-intercept form of the equation is $y = mx + b$, where $m$ is the slope (rate of change) and $b$ is the y-intercept (starting value). Here, $m = 8$ (cost per movie channel) and $b = 24$ (basic service cost), so the equation is $y = 8x + 24$.
