| Hours Studied (x) | 0.5 | 1 | 1.5 | 2 | 2.5 | 3 | 4 | |------------------|----|----|----|----|----|----|----| | Test Score (y) | 55 | 65 | 70 | 75 | 80 | 85 | 95 |
b) Write the equation of your line: ___________________ lesson 2 homework practice lines of best fit
c) Predict the y-value when x = 10: ________ | Hours Studied (x) | 0
b) Use two points from your line of best fit to find the slope. Show your work. (2, 4), (3, 5), (4, 7), (5, 8),
(If no grid is available, describe where your line passes through two approximate points.) An ice cream shop records daily high temperature (°F) and ice cream sales ($).
(2, 4), (3, 5), (4, 7), (5, 8), (6, 9), (7, 12), (8, 14)
e) Is it reasonable to use this line to predict sales at ? Why or why not? 5. Challenge – Interpret the Line A student drew a line of best fit for a scatter plot with the equation: [ y = -2.5x + 45 ]
