Question

bria starts with $8 in her account. she earns $12 per hour babysitting and deposits the earnings into her account. now find the slope, or the rate of change. you can think of this as: by how much does the amount in brias account change for every additional hour that she works? vertical intercept: 8 slope: \boxed{}

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 $(x_1,y_1)=(0,8)$ and $(x_2,y_2)=(1,20)$

Step3: Calculate slope

$m = \frac{20 - 8}{1 - 0} = \frac{12}{1} = 12$

Answer:

12
