Question

a machinist measures the thickness of a grinding pad every week. the graph shows how many millimeters the grinding pad has worn down. answer parts a and b. a. what is the slope of the line? the slope is
(type an integer or a simplified fraction.)

Explanation:

Step1: Identify two points on the line

The line passes through $(0, 0)$ and $(8, 40)$.

Step2: Apply slope formula

Slope $m = \frac{\text{Change in } y}{\text{Change in } x} = \frac{y_2 - y_1}{x_2 - x_1}$
Substitute $(x_1,y_1)=(0,0)$ and $(x_2,y_2)=(8,40)$:
$m = \frac{40 - 0}{8 - 0} = \frac{40}{8}$

Step3: Simplify the fraction

$\frac{40}{8} = 5$

Answer:

5
