Hatshy [7]

Answer:

An equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2

Step-by-step explanation:

Speed of Byron = 4 miles / hour

Distance traveled in x hours = $Speed \times time$

Distance traveled in x hours = 4x

We are given that After half an hour of running, he is 2 miles from home

So, Total distance = 4x+2

So, y = 4x+2

Hence an equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
