1. Encuentra la pendiente \( m \) usando los puntos (10, 110) y (15, 135):

m = \frac{135 - 110}{15 - 10} = \frac{25}{5} = 5

2. Usa el punto (10, 110) para determinar el valor de \( b \):

110 = 5 \cdot 10 + b
110 = 50 + b
b = 60

3. La ecuación lineal es:

y = 5x + 60

4. Calcula el costo de producir 90 artículos al día:

y = 5(90) + 60
y = 450 + 60
y = 510

5. Por lo tanto, el costo de producir 90 artículos al día es:

y = 510

A popular cell phone family plan provides 1500 minutes. It charges 89.99/month for the first 2 lines and 9.99 for every line after that. Unlimited text messages for all phone lines costs $30.00/month, and Internet costs $10.00/month per phone line. If a family with a $200 monthly budget buys this plan and signs up for unlimited text messaging and Internet on each phone line, how many cell phone lines can they afford? Use an inequality to solve this problem. Graph your solution on the number line and explain the meaning of your graph in a sentence.
