Question

Please Help with Algebra 1 ???

Answer 1

Part I: Read each description of real-world situations represented by equations of lines in
different forms. Then use the equations to answer the questions.

1. A research scientist is studying how fast a certain type of bacteria grows. She measures the number of bacteria present in a Petri dish each hour for several hours. After analyzing the results, she notices that the number of bacteria grows at a steady rate following a linear pattern of growth. The scientist writes the equation of the line below to model the growth of the bacteria, where y represents the number of bacteria present after x hours.

y - 96 = 18 (x-5)

Answer 2

In what linear form is the equation written?


Use the equation to identify the slope of the line. What does the slope represent in
this situation?

Use the equation to identify a point on the line. What does the point represent in this
situation?
