Question

plant growth
the graph shows the number of centimeters a particular plant grows over time. 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 the origin \((0,0)\) and another point, say \((4, 8)\) (by looking at the graph, when \(x = 4\) weeks, \(y = 8\) cm).

Step2: Use the slope formula \(m=\frac{y_2 - y_1}{x_2 - x_1}\)

Here, \((x_1,y_1)=(0,0)\) and \((x_2,y_2)=(4,8)\). So \(m=\frac{8 - 0}{4 - 0}=\frac{8}{4}=2\).

Answer:

\(2\)
