Question

a restaurant charges $12 for a plain medium pizza and $1.50 for every topping added. what is the slope of line n? \\(\text{slope}=\frac{\text{vertical distance}}{\text{horizontal distance}}\\) \\(=\square\\)

Explanation:

Step1: Identify two points on line

Use points $(2, 15)$ and $(4, 18)$

Step2: Calculate vertical distance

$\Delta y = 18 - 15 = 3$

Step3: Calculate horizontal distance

$\Delta x = 4 - 2 = 2$

Step4: Compute slope via ratio

$\text{Slope} = \frac{\Delta y}{\Delta x} = \frac{3}{2}$

Answer:

$1.5$
