the amount of time of the two trips is a proportional relationship
<h3>What is proportional relationship?</h3>
mathematical expressions are said to be proportional if there unit rate are equal. this means that the expressions will give similar results when similar values are substituted into the equation.
<u>solution:</u>
Driving 7 hrs within 385 miles represents a unit rate of 385 / 7 = 55 miles per hour or 55 mph
while 3 hrs in 165 miles represents a unit rate of 165 / 3 = 55 mph
since both situations gave similar speed in miles per hour they are said to have a proportional relationship.

Answer:
1). y = -7/5x - 4
2). y = 1/5x - 5
Step-by-step explanation:
In this question, we have to write the slope-intercept form of the given information.
Slope intercept form is: y = mx + b
Our "m" value is our slope and our "b" value is our y-intercept.
With that knowledge, we can plug in our given information to the slope-intercept equation:
1) slope = -7/5, y-intercept = -4
Plug -7/5 to "m" and -4 to "b"
y = -7/5x - 4
2) slope = 1/5, y-intercept = -5
Plug 1/5 to "m" and -5 to "b"
y = 1/5x - 5
