A.2B·Algebra 1·Linear Functions
Writing Linear Equations in the real world
Write linear equations in slope-intercept form given a slope and a point, or two points.
Transfer evidence, not just familiar practice
Correctly solve different fresh variations at least 24 hours after your first correct transfer response. Reviewing the same challenge again does not count as fresh retention evidence.
You can explore every situation now. Practice unlocks after you retain A.3C.

Equipment and greenhouse management
A rental coordinator has two cost data points, and a greenhouse manager records a steady temperature decline over four hours. Both need a linear model for forecasting.
Why this TEKS matters
Two points determine slope, and slope plus one point determines a linear equation that can be used for planning.
Challenge 2
Model greenhouse cooling
Calculate the hourly temperature change and identify the slope in the model.

Refilling and parking costs
A tank starts partially filled and refills at a steady rate, while a parking garage combines an entry fee with a constant hourly charge.
Why this TEKS matters
Slope-intercept form separates a starting value from a constant rate, even when the starting fee must be inferred from two bills.
Challenge 3
Model a refilling tank
Write volume as the initial amount plus the refill rate multiplied by time.
Challenge 4
Decode a parking bill
Use the three-hour and seven-hour totals to determine the entry fee and hourly rate.
