Write a linear function f with the values f(−1)=8 and f(5)=6.<br><br> A function is f(x)=
german

9514 1404 393

Answer:

  f(x) = -1/3x +23/3

Step-by-step explanation:

You can use the linear regression function of a graphing calculator or spreadsheet to show you the equation of the line through these points:

  f(x) = -1/3x +23/3

__

Approaching this in the usual way, we recognize we have points ...

  (-1, 8) and (5, 6)

The slope of the line through those points is ...

  m = (y2 -y1)/(x2 -x1)

  m = (6 -8)/(5 -(-1)) = -2/6 = -1/3

Then the point-slope equation of the line is ...

  y - 8 = -1/3(x +1)

Adding 8 gives us a form we can use for a function definition:

  f(x) = -1/3(x +1) +8

  f(x) = -1/3x +7 2/3

Given points (0,0) and (3,6), find the point which partitions the segment into 3:2.
sertanlavr [38]
Dividing a number by the ratio 3:2 means dividing into 3+2 = 5 parts

Let (0, 0) be (x₁, y₁) and (3, 6) be (x₂, y₂)

Find one part of the share for each axes, we do
\frac{x_1+x_2}{5} = \frac{0+3}{5}= \frac{3}{5} =0.6
\frac{y_1+y_2}{5}= \frac{0+6}{5}= \frac{6}{5}=1.2

Then multiplying the one part back into 3: 2, we have
for the x - axis ⇒ (3×0.6) : (2×0.6) = 1.8: 1.2
for the y - axis ⇒ (3×1.2) : (2×1.2) = 3.6: 2.4

The coordinate that divides the segment into 3 parts and 2 parts is (1.8, 3.6)

Correct answer: A
