A cab company charges a base rate of $\$ 1.50$ plus 15 cents per minute. Let y be the cost in dollars of using the cab for $x$ minutes. Find the slope-intercept form of the equation.
A) $y = 1.50 x + 0.15$
B) $y = 0.15 x + 1.50$
C) $y = 0.15 x - 1.50$
D) $y = 1.50 x - 0.15$

The slope-intercept form of a linear equation is $y = mx + b$, where $m$ is the slope (rate of change) and $b$ is the y-intercept (the starting value when $x = 0$). In this case, the cost increases by 15 cents (0.15 dollars) per minute, making 0.15 the slope, and the base rate of $1.50 is the y-intercept. Therefore, the correct equation is $y = 0.15x + 1.50$.
