To express the total monthly cost \( Y \) as a function of the number of texts sent \( X \), we can use the slope-intercept form of a linear equation, which is \( Y = mX + b \). In this case, the cost per text is 0.25 dollars, making the slope \( m \) equal to 0.25. Since there is no fixed monthly fee, the y-intercept \( b \) is 0. Therefore, the equation representing this plan in slope-intercept form is \( Y = 0.25X + 0 \). This indicates that for each text sent, the total cost increases linearly by 25 cents.
In 4-5 sentences Explain what If Y represents the total monthly cost and X represents the number of texts sent, what equation in slope-intercept form represents this plan?
The sentence bellow has the numbers you need
If I send 100 text messages in a month and each text costs 25 cents, I can figure out the total cost by multiplying the number of texts by the price per text. So, I would do 100 texts times 0.25 cents (which is 25 dollars). That equals 25 dollars, which is my total monthly cost for texting. To make it simple, just think of it like paying a quarter for each text, and if I send a lot, it adds up pretty quick!
