Answer:
<h2>y = 6x + 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em />
We have the slope <em>m = 6</em>, and the y-intercept <em>b = 2</em>.
Substitute:

Convert 15% into a decimal. (0.15) Then multiply that by 550.
Distance = Average speed * Time = 48*10 = 480 miles
So, they drove for 480 miles
3/4's obviously because the percentage is bigger.
You add them and then divide by how many numbers there are.
a. (3+43)/2 = 23
b. 0
c. -1
