 Question 612404: For the function f(x), f(2.3)= -7.2 and f(8.4)= 9.1. What is the equation for the function f(x)?Answer by stanbon(57282)   (Show Source): You can put this solution on YOUR website!For the function f(x), f(2.3)= -7.2 and f(8.4)= 9.1. What is the equation for the function f(x)? ----- slope = (9.1--7.2)/(8.4-2.3) = 16.3/6.1 = 163/61 -------- Form: y = mx + b Solve for "b": 9.1 = (163/61)8.4 + b b = 9.1 - 22.45 = -13.35 ------ Equation: y = (163/61)x - 13.35 ======================= Cheers, Stan H. ================
