Pre-Algebra PSSA Practice Test Slides and Rainfall Measurement Analysis
In this content, you will find a series of slides for a PSSA practice test in Pre-Algebra. Additionally, it includes a scenario where Bill measures rainfall using a rain gauge, requiring analysis of rainfall data and the creation of a slope-intercept equation. The scenario also asks to interpret the meaning of a zero slope in the context of the rainfall measurement.

PSSA PRACTICE TEST Pre-Algebra
Open Ended Bill used a rain gauge to measure how much rain fell, in centimeters (cm), during a rainfall. The rain fell at the same rate throughout the first 180 minutes of the rainfall. A. Complete the table below with the number of minutes it took for 9 cm of rain to fall and the number of centimeters of rain that fell through 150 minutes.
Open Ended Bill used a rain gauge to measure how much rain fell, in centimeters (cm), during a rainfall. The rain fell at the same rate throughout the first 180 minutes of the rainfall. B. Write an equation in slope-intercept form to describe the relationship between the time (?), in minutes, and the amount of rain(?), in cm.
Open Ended Bill used a rain gauge to measure how much rain fell, in centimeters (cm), during a rainfall. The rain fell at the same rate throughout the first 180 minutes of the rainfall. C. After 280 minutes, the slope of the graph is 0. Explain what the slope of zero means in this situation.
