Question

aaron starts with $0 in his bank account. he earns $12 per hour babysitting and deposits the earnings into his account. now find the slope, or the rate of change, in this situation. you can think of this as: by how much does the amount in aarons account change for every additional hour that he works? vertical intercept: 0 slope:

Explanation:

Step1: Recall slope formula

Slope $m = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}$

Step2: Pick two points from graph

Use $(x_1,y_1)=(0,0)$ and $(x_2,y_2)=(1,12)$

Step3: Calculate slope

$m = \frac{12 - 0}{1 - 0} = 12$

Answer:

12
