Chapter 5: Q75. (page 228)

TRANSPORTATION For Exercises 74–76, refer to the graph at the right. (Lesson 2-5)
. Write a prediction equation.

Short Answer

Expert verified

The prediction equation is $y = 0.1 x + 4.9$ .

Step by step solution

Step-1 – Given

The given image is:

Step-2 – To determine

We have to find the prediction equation.

Step-3 – Calculation

The scatter plot for (x, y) is:

From the graph we see that the points are almost on a line.

To find the slope we take first two points (0, 4.9) and (5, 5.4).

Slope is = m = $\frac{(5.4 - 4.9)}{5 - 0} = 0.1$ .

y-intercept = b = 4.9.

So, the equation is: $\begin{array}{l} y = m x + b \\ y = 0.1 x + 4.9 \end{array}$

Hence, the prediction equation is $y = 0.1 x + 4.9$ .
