Question

oliver starts with 10 dollars in his account. he earns 5 dollars per hour working at a store and deposits the earnings into his account. leo starts with -15 dollars in his account. he earns 5 dollars per hour working at a store and deposits the earnings into his account. what are the vertical intercepts of the lines? oliver: $d = 10 + 5x$ the slope of oliver’s line is 5. the vertical intercept of oliver’s line is \boxed{}. leo: $d = -15 + 5x$ the slope of leo’s line is 5. the vertical intercept of leo’s line is \boxed{}.

Explanation:

Step1: Recall slope-intercept form

A linear equation is $y = mx + b$, where $b$ is the vertical intercept.

Step2: Identify Oliver's vertical intercept

Oliver's equation: $d = 10 + 5x$. Here, $b=10$.

Step3: Identify Leo's vertical intercept

Leo's equation: $d = -15 + 5x$. Here, $b=-15$.

Answer:

The vertical intercept of Oliver's line is 10
The vertical intercept of Leo's line is -15
