Slope-Intercept Form Questions?

• 1. Sandra wants to send her pet Rondo to doggy day care. Below is a table showing her total costs after each day of care. Using this information, find the slope and y-intercept. http://i46.tinypic.com/23hm1zl.jpg A) m = 1/27, b = 41 B) m = 217/5, b = 95 C) m = 27, b = 41 Using the information and your answers from above find the equation that represents the relationship between the number of days in day care and the total cost. A) y = 27x + 41 B) y = 41x + 27 C) y = 1/27x + 41 D) y = 217/5x + 95 Use your answer from above to determine how much Sandra will spend on doggy day care after 11 days. A) $478 B) $338 C) $41.40 D) $572.40 Thanks to whoever helps the most, and 10 points to you!

• Answer:

  slope m = (176 - 149) / (5 - 4) = 27 / 1 = 27 m = 27 --------- y = mx + b 95 = 27.(2) + b 95 = 54 + b b = 41 --------- So, y = 27x + 41 ------------------------ y = 27.(11) + 41 = 338 Sandra will spend $ 338.00 on doggy day care after 11 days. --------------------------------------… Hope this helps!
