If f (x) is linear, f ( - 1) = 9, and f (2) = - 24, find f (x).

Answer: Equation of st line is Y = - 9X + 141

Step-by-step explanation: Given Y = 24 when X = 13 and Y = 87 when X = 6

Let the equation be Y = mX + C

24 = m*13 + C

and 87 = m * 6 + C

Give m = - 9 and C = 141

Equation of st line is Y = - 9X + 141
