Answer:
Step-by-step explanation:
Let x represent the number of text messages that Alyssa sent.
Let y for the total amount charged for x messages sent.
Looking at the table showing her last 3 bills,
Total amount charged for 256 messages is $38.40. Charge per text message = 38.4/256 = $0.15
Total amount charged for 177 messages is $26.55. Charge per text message = 177/26.55 = $0.15
Total amount charged for 209 messages is $31.35. Charge per text message = 209/31.35 = $0.15
The charge is constant.
Therefore,
The slope, m = 0.15
Therefore, the equation of the line is
y = mx + c
Intercept, c = 0. The equation becomes
y = 0.15x
Alyssa is charged $0.15 for each text message.
