Answer:
Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Slope-intercept form:
where m is the slope and b is the y-intercept (the value of y when x is 0)
<u>1) Determine the slope (m)</u>
<u />
where two points that the line passes through are 
and 
Plug in the given points (1,-3) and (-3,17)
Therefore the slope of the line is -5. Plug this into :
<u>2) Determine the y-intercept (b)</u>
Plug in one of the given points and solve for b
Add 5 to both sides of the equation to isolate b
Therefore, the y-intercept of the equation is 2. Plug this back into :
I hope this helps!
Answer: c. (1,-2,-3); 4 sqrt 7.
Step-by-step explanation:
2/5 is the slope of the equation.
Here is the solution for the given problem above.
Given: 1 2/5 hour = time it takes to download a movie
5 1/4 hours = total hours for the download
? = number of movies downloaded
First, we need to simplify 1 and 2/5 hour, which is 1.4 hour, and 5 1/4 is 5.25 hours. Next, to get the number of movies downloaded, we divide 5.25 by 1.4 and the result is 3.75. Round this off to a whole number and we get 4. Approximately, you were able to download 4 MOVIES. Hope this helps.
