Question

the graph below represents a Jaya's earnings in dollars and cents Y for working X hours find the rate of change .

Answer 1

Step-by-step explanation:

The rate of change can be calculated as:

`m=(y_2-y_1)/(x_2-x_1)`

Where (x₁, y₁) and (x₂, y₂) are two points in the line.

So, replacing (x₁, y₁) by (10, $289) and (x₂, y₂) by (20, $578), we get:

`m=\frac{\text{ \$578 - \$289}}{20-10}=\frac{\text{ \$289}}{10}=\text{ \$28.9 per hour}`

Then, the rate
