Find the linear approximation of the data that passes through the points 5,3 and 20,6

Step-by-step explanation:

The linear approximation of the data that passes through the points (5,3) and (20,6).

We need to find the equation of line.

If a line passes through two points, then the equation of line is

The line passes through (5,3) and (20,6). So, the equation of line is

Add 3 on both sides.

Therefore, the equation of linear approximation is .

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
