Question

Question 14 (1 point) Write an equation in the form y = mx + b for the average cost, y, of a textbook x years after 1990. Use the data points (0, 38) and (8, 86) to find the equation. Then use the equation to predict the average cost in 2012. 1) y = 6x + 38; the cost in 2012 is $170 2) y = 6x + 38; the cost in 2012 is $86 3) y = 38x + 6; the cost in 2012 is $234 4) y = 38x + 6; the cost in 2012 is $842

Step 1

Step 1: Find the slope using the formula: $m = \frac{Y_2 - Y_1}{X_2 - X_1}$ Given points: (0, 38) and (8, 86) $m = \frac{86 - 38}{8 - 0} = \frac{48}{8} = 6$ Show more…
